va Redetermination and new description of the crystal structure of vanthoffite, Na6Mg(SO4)4 By scripts.iucr.org Published On :: 2020-05-01 The crystal structure of vanthoffite {hexasodium magnesium tetrakis[sulfate(VI)]}, Na6Mg(SO4)4, was solved in the year 1964 on a synthetic sample [Fischer & Hellner (1964). Acta Cryst. 17, 1613]. Here we report a redetermination of its crystal structure on a mineral sample with improved precision. It was refined in the space group P21/c from a crystal originating from Surtsey, Iceland. The unique Mg (site symmetry overline{1}) and the two S atoms are in usual, only slightly distorted octahedral and tetrahedral coordinations, respectively. The three independent Na atoms are in a distorted octahedral coordination (1×) and distorted 7-coordinations intermediate between a `split octahedron' and a pentagonal bipyramid (2×). [MgO6] coordination polyhedra interchange with one half of the sulfate tetrahedra in <011> chains forming a (100) meshed layer, with dimers formed by edge-sharing [NaO7] polyhedra filling the interchain spaces. The other [NaO7] polyhedra are organized in a parallel layer formed by [010] and [001] chains united through edge sharing and bonds to the remaining half of sulfate groups and to [NaO6] octahedra. The two types of layers interconnect through tight bonding, which explains the lack of morphological characteristics typical of layered structures. Full Article text
va Crystal structure and Hirshfeld surface analysis of 4,4'-(propane-1,3-diyl)bis(4H-1,2,4-triazol-1-ium) pentafluoridooxidovanadate(V) By scripts.iucr.org Published On :: 2020-05-01 In the structure of the title salt, (C7H12N6)[VOF5], second-order Jahn–Teller distortion of the coordination octahedra around V ions is reflected by coexistence of short V—O bonds [1.5767 (12) Å] and trans-positioned long V—F bonds [2.0981 (9) Å], with four equatorial V—F distances being intermediate in magnitude [1.7977 (9)–1.8913 (9) Å]. Hydrogen bonding of the anions is restricted to F-atom acceptors only, with particularly strong N–H...F interactions [N...F = 2.5072 (15) Å] established by axial and cis-positioned equatorial F atoms. Hirshfeld surface analysis indicates that the most important interactions are overwhelmingly H...F/F...H, accounting for 74.4 and 36.8% of the contacts for the individual anions and cations, respectively. Weak CH...F and CH...N bonds are essential for generation of three-dimensional structure. Full Article text

va Absolute structure of the chiral pyrrolidine derivative (2S)-methyl (Z)-5-(2-tert-butoxy-1-cyano-2-oxoethylidene)pyrrolidine-2-carboxylate, a compound with low resonant scattering By scripts.iucr.org Published On :: 2019-10-04 The enantiopure monopyrrolidine derivative (2S)-methyl (Z)-5-(2-tert-butoxy-1-cyano-2-oxoethylidene)pyrrolidine-2-carboxylate, C13H18N2O4, (1), represents a potential ligand and an attractive intermediate for the synthesis of chiral metal complexes. At the molecular level, the compound features an intramolecular N—H⋯O hydrogen bond; neighbouring molecules interact via N—H⋯N contacts to form chains along [100]. Due to its elemental composition, resonant scattering of the target compound is entirely insignificant for diffraction experiments with Mo Kα and small even for Cu Kα radiation. A preliminary study with the harder radiation type confirmed the chiral space group and the suitability of the single crystal chosen; as expected, the results concerning the absolute structure remained completely inconclusive. A second data collection with the longer wavelength gave satisfactory quality indicators for the correct handedness of the molecule, albeit with high standard uncertainties. The absolute configuration has been assessed independently: CD spectra for both enantiomers of the target molecule were calculated and the spectrum for the S-configured stereoisomer was in agreement with the experiment. The Cotton effect of (1) may be ascribed to π–π* transitions from HOMO to LUMO and from HOMO to LUMO+1. As both independent techniques agree with respect to the handedness of the target molecule, the absolute structure may be assigned with a high degree of confidence. Full Article text
va Conversion of 3-amino-4-arylamino-1H-isochromen-1-ones to 1-arylisochromeno[3,4-d][1,2,3]triazol-5(1H)-ones: synthesis, spectroscopic characterization and the structures of four products and one ring-opened derivative By scripts.iucr.org Published On :: 2020-04-20 An efficient synthesis of 1-arylisochromeno[3,4-d][1,2,3]triazol-5(1H)-ones, involving the diazotization of 3-amino-4-arylamino-1H-isochromen-1-ones in weakly acidic solution, has been developed and the spectroscopic characterization and crystal structures of four examples are reported. The molecules of 1-phenylisochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H9N3O2, (I), are linked into sheets by a combination of C—H⋯N and C—H⋯O hydrogen bonds, while the structures of 1-(2-methylphenyl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C16H11N3O2, (II), and 1-(3-chlorophenyl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H8ClN3O2, (III), each contain just one hydrogen bond which links the molecules into simple chains, which are further linked into sheets by π-stacking interactions in (II) but not in (III). In the structure of 1-(4-chlorophenyl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, (IV), isomeric with (III), a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds links the molecules into sheets. When compound (II) was exposed to a strong acid in methanol, quantitative conversion occurred to give the ring-opened transesterification product methyl 2-[4-hydroxy-1-(2-methylphenyl)-1H-1,2,3-triazol-5-yl]benzoate, C17H15N3O3, (V), where the molecules are linked by paired O—H⋯O hydrogen bonds to form centrosymmetric dimers.

va Polymorphism and phase transformation in the dimethyl sulfoxide solvate of 2,3,5,6-tetrafluoro-1,4-diiodobenzene By scripts.iucr.org Published On :: 2020-04-30 A new polymorph (form II) is reported for the 1:1 dimethyl sulfoxide solvate of 2,3,5,6-tetrafluoro-1,4-diiodobenzene (TFDIB·DMSO or C6F4I2·C2H6SO). The structure is similar to that of a previously reported polymorph (form I) [Britton (2003). Acta Cryst. E59, o1332–o1333], containing layers of TFDIB molecules with DMSO molecules between, accepting I⋯O halogen bonds from two TFDIB molecules. Re-examination of form I over the temperature range 300–120 K shows that it undergoes a phase transformation around 220 K, where the DMSO molecules undergo re-orientation and become ordered. The unit cell expands by ca 0.5 Å along the c axis and contracts by ca 1.0 Å along the a axis, and the space-group symmetry is reduced from Pnma to P212121. Refinement of form I against data collected at 220 K captures the (average) structure of the crystal prior to the phase transformation, with the DMSO molecules showing four distinct disorder components, corresponding to an overlay of the 297 and 120 K structures. Assessment of the intermolecular interaction energies using the PIXEL method indicates that the various orientations of the DMSO molecules have very similar total interaction energies with the molecules of the TFDIB framework. The phase transformation is driven by interactions between DMSO molecules, whereby re-orientation at lower temperature yields significantly closer and more stabilizing interactions between neighbouring DMSO molecules, which lock in an ordered arrangement along the shortened a axis.

va California Biotech Partners for Manufacture of COVID-19 Vaccine Candidate By www.streetwisereports.com Published On :: Wed, 06 May 2020 00:00:00 PST Source: Streetwise Reports 05/06/2020 Arcturus Therapeutics Holdings' arrangement is explained and commented on in an H.C. Wainwright & Co. report.In a May 4 research note, H.C. Wainwright & Co. analyst Ed Arce reported that Arcturus Therapeutics Holdings Inc. (ARCT:NASDAQ) formed a partnership with Catalent Inc. (CTLT:NYSE), which "raises the profile of LUNAR-COV19 as a leading vaccine candidate." Arce reviewed Catalent's contribution to the partnership. The global contract development and manufacturing organization is to manufacture Arcturus' messenger RNA (mRNA) LUNAR-COV19 for protection against SARS-CoV-2 to be used first for human clinical trials and potentially, eventually commercially. As for timing, Arce noted, San Diego, Calif.-based Arcturus intends to transfer its vaccine technology to Catalent this month and expects Catalent to manufacture the first batches of LUNAR-COV19 by June 2020. "Critically, Arcturus continues to anticipate initiation of Phase 1 testing of LUNAR-COV19 in the summer of 2020," Arce highlighted. Catalent is to produce the vaccine at its biomanufacturing facility in Madison, Wisc. "This facility utilizes Catalent's flex-suite, a current good manufacturing practice manufacturing suite, that can produce batches at multiple scales and support Arcturus' proprietary mRNA manufacturing process," explained Arce. Obtaining the vaccine from one facility domestically versus multiple entities worldwide should result in several benefits, Arce continued. They include easy development and production, accelerated delivery and improved costs. Arcturus believes Catalent can produce millions of doses of LUNAR-COV19 mRNA in 2020 and, if need be, hundreds of millions of doses each year subsequently for use globally. Arce pointed out that LUNAR-COV19 differentiates itself from other similar vaccine candidates in that the technology and delivery platform behind it deliver an "extraordinarily low dose (perhaps 2 micrograms)" in "a potential single shot." H.C. Wainwright has a Buy rating and a $62 per share price target on Arcturus, the stock of which is currently trading at about $42.12 per share.

va NuLegacy Gold Receives Strong Vote of Confidence in Value of Its Flagship Red Hill Project in Nevada's Cortez Trend By www.streetwisereports.com Published On :: Thu, 07 May 2020 00:00:00 PST Source: Peter Epstein for Streetwise Reports 05/07/2020 Peter Epstein of Epstein Research looks into the Gross Overriding Royalty that just changed hands on the company's flagship Red Hill project, and discusses what it means for the firm.In late April, Metalla Royalty & Streaming acquired two royalties, one of which was a Gross Overriding Royalty (GOR) on NuLegacy Gold Corporation (NUG:TSX.V; NULGF:OTCQX) flagship Red Hill project, a Carlin-style deposit in Nevada's world-famous Cortez trend. To be clear, this was a transaction between Metalla and a private company; no cash or other remuneration flowed to NuLegacy. However, this news is still exciting and thought provoking as it pertains to a potential (implied) valuation of Red Hill. So much so, thatCEO/director of Finance and MarketingAlbert Matter put out this press release highlighting it. {corporate presentation} Metalla's news is applicable to NuLegacy for a number of reasons. Let me start by saying I know the Metalla team, I've written about the company several times (although not recently). This is a smart, hard-working, market-savvy group, with global experience, integrity and expertise. When dealing in streams and royalties, it's all about industry connections, market knowledge and deal flow. Metalla has that and is up to its eyeballs in deal flow (deals it can make or pass on). Takeaways on implied valuation of NuLegacy's Red Hill project? That's why this news is so interesting. It represents a reliable, unbiased vote of confidence in NuLegacy's Red Hill project. I was able to track down the president, CEO and a director of Metalla, Mr. Brett Heath, to ask him about his team's view of NuLegacy, their management and technical teams, and the Red Hill project, "The Red Hill project is very interesting due to its location & position within the Cortez trend of Nevada that hosts globally significant mines & projects, specifically Cortez Hills, Pipeline & Goldrush. Although many near-surface deposits have been discovered, several blind deposits similar to Goldrush have yet to be found. "NuLegacy's Rift Anticline is a promising new drill target, a chance to discover a large, high-grade deposit. The close proximity of Red Hill to Goldrush heavily influenced our understanding of the geology at Red Hill. Specifically, it allowed us to better understand that the Rift Anticline has similar stratigraphy to Goldrush, and similar mineralization events nearby." Investors, shareholders and analysts are trying to figure out what (if any) read-throughs there are in terms of the valuation of the Red Hill project. From the press release: "Valuing Gross Overriding Royalties ("GORs") is a complicated business made easier in this instance by the straightforward nature of the [transaction] . prorating the US$4 million purchase price for the total of 2% GOR that was acquired . values a 1% GOR in the Red Hill project at ~US$2 million." What this valuation exercise boils down to is how does the value of a 1% GOR compare to a conventional working interest in the same project? GORs are highly case specific, so I will give a range of possibilities. Many factors make GORs unique, but a rule of thumb is that a 1% GOR equates to a 5% working interest. However, due to the unknown terms of this particular GOR, let's assume that the 1% GOR is equal to between a 5% and 10% working interest. By extending the range higher than 5%, more conservative valuations for Red Hull are obtained. In the chart below one can see that the implied ~US$2 million paid for a 1% GOR equals C$2.8 million at the current exchange rate. Therefore, Red Hill's indicative valuation could be viewed as C$28 million to C$56 million, or C$0.08 to C$0.15 per share. Currently, the stock's trading at C$0.07. The company has a cash balance of C$4.5 million. {see corporate presentation}. I believe the C$0.08 to C$0.15/share range is conservative because Metalla's purchase of the GOR had a built-in profit expectation. The true ascribed value of a 1% GOR on the Red Hill project might be higher than C$2.8 million. A true vote of confidence in NuLegacy Gold Perhaps more important than an implied (subjective) valuation of Red Hill are the following takeaways. First, Metalla not only likes Red Hill, it must also feel good about the long-term prospects for Nevada and the U.S. Metalla looks at hundreds of deals a year from all over the world. Management can, and does, invest in dozens of jurisdictions. Yet, in April 2020, it chose the U.S., . Nevada . the Cortez Trend . Second, it chose a project that's pre-maiden resource. Remember, Metalla has paid out ~C$2.8 million, but doesn't make a penny of that back unless it re-sells some or all of the GOR it acquired, or Red Hill reaches commercial production. Therefore, I argue that investing at this relatively early stage is a stamp of approval in the extensive work done to date at Red Hill. That Metalla chose to deploy capital in a gold asset rather than a silver asset, despite the gold-silver ratio being near an all-time high (over 110 to 1) seems promising. Finally, it chose the U.S. at a time when the currencies of Mexico, Australia, Canada and others have weakened considerably vs. the U.S. dollar, making exploration cheaper in those countries. One must have conviction to choose Red Hill over dozens of public and private, pre-maiden resource, projects around the globe. In the end, a good project in a great jurisdiction is only as prospective as its technical/management teams. NuLegacy has prudently advanced Red Hill in good times and bad. For most of NuLegacy's existence, the gold price traded between about $1,050 and $1,400/oz. Gold price at $1,730/oz. is a game-changer . Now gold is hovering around $1,730/oz after almost touching $1,800/oz in March. This is a game-changer for juniors like NuLegacy that have tremendous blue-sky potential, (look at neighboring mines and development projects, some of the best on the planet) but like most juniors, have limited funding to conduct aggressive drill programs in a strong gold price environment. A savvy company betting on the Red Hill project is yet another indication that the time has come for precious metal players to become more active in M&A. The day that Barrick commits its deep experience (and deep pockets!) to NuLegacy's Red Hill, all royalties held on that project would soar in value. Why? The timeline to potential production would be shortened, perhaps by years, (more drilling, less investor hand holding, perhaps skipping a PEA or a PFS). The scope of the project would become largermore drilling across a wider footprint (a 108 sq. km land package). The value of the royalties could double, triple, quadruple . who knows? The share price at which NuLegacy gets taken out could also be meaningfully stronger. After all the company has been through, I don't think the Board would sell the company below C$0.30/share. At least not with the gold price at $1,730/oz (or higher). Readers are reminded that C$1.5 billon OceanaGold Corp. & giant natural resources fund Tocqueville own a combined 21.5% of the company. Might there be a bidding war for NuLegacy? In a best case example then, there could be multiple bidders for NuLegacy. This is not nearly as crazy as it sounds, especially if the gold price keeps going up, or if the next (fully funded) drill program hits the mark. If Barrick were to make a move, OceanaGold, Newmont, or even Tocqueville (they could hold out for higher price) might have something to say about it. Those entities, and/or other mid-tiers/majors in Nevada or around the world would keep Barrick honest. Over the years NuLegacy has been in touch with several well-known names, but I never know who they're talking with at any given time. Make no mistake, Barrick is best positioned by virtue of having the most synergies with Red Hill, so it can afford to pay several more pennies per share if need be. That's how a share price of C$0.30+ becomes possible. Bottom line, NuLegacy Gold (TSX-V: NUG) / (OTCQX: NULGF) is a high-risk exploration play, but I believe a good speculation. There's no better time to be buying high-risk exploration than when the prices of the metals being explored for are moving up. As more attention is drawn to NuLegacy, its team, the undisputed safety of Nevada, the prolific nature of the Cortez Trend, etc., I think there's compelling relative and absolute value here that readers should consider investigating further.
