The crystal structure of (RS)-7-chloro-2-(2,5-di­meth­oxy­phen­yl)-2,3-di­hydro­quinazolin-4(1H)-one: two hydrogen bonds generate an elegant three-dimensional framework structure

In the title compound, C61H15ClN2O3, the heterocyclic ring adopts an envelope conformation, folded across the N⋯N line, with the 2,5-di­meth­oxy­phenyl unit occupying a quasi-axial site. There are two N—H⋯O hydrogen bonds in the structure: one hydrogen bond links mol­ecules related by a 41 screw axis to form a C(6) chain, and the other links inversion-related pairs of mol­ecules to form an R22(8) ring. The ring motif links all of the chains into a continuous three-dimensional framework structure. Comparisons are made with the structures of some related compounds.

Diversifying molecular and topological space via a supramolecular solid-state synthesis: a purely organic mok net sustained by hydrogen bonds

A three-dimensional hydrogen-bonded network based on a rare mok topology has been constructed using an organic molecule synthesized in the solid state. The molecule is obtained using a supramolecular protecting-group strategy that is applied to a solid-state [2+2] photodimerization. The photodimerization affords a novel head-to-head cyclo­butane product. The cyclo­butane possesses tetrahedrally disposed cis-hydrogen-bond donor (phenolic) and cis-hydrogen-bond acceptor (pyridyl) groups. The product self-assembles in the solid state to form a mok network that exhibits twofold interpenetration. The cyclo­butane adopts different conformations to provide combinations of hydrogen-bond donor and acceptor sites to conform to the structural requirements of the mok net.

The many flavours of halogen bonds – message from experimental electron density and Raman spectroscopy

Experimental electron-density studies based on high-resolution diffraction experiments allow halogen bonds between heavy halogens to be classified. The topological properties of the electron density in Cl⋯Cl contacts vary smoothly as a function of the inter­action distance. The situation is less straightforward for halogen bonds between iodine and small electronegative nucleophiles, such as nitro­gen or oxygen, where the electron density in the bond critical point does not simply increase for shorter distances. The number of successful charge–density studies involving iodine is small, but at least individual examples for three cases have been observed. (a) Very short halogen bonds between electron-rich nucleophiles and heavy halogen atoms resemble three-centre–four-electron bonds, with a rather symmetric heavy halogen and without an appreciable σ hole. (b) For a narrow inter­mediate range of halogen bonds, the asymmetric electronic situation for the heavy halogen with a pronounced σ hole leads to rather low electron density in the (3,−1) critical point of the halogen bond; the properties of this bond critical point cannot fully describe the nature of the associated inter­action. (c) For longer and presumably weaker contacts, the electron density in the halogen bond critical point is only to a minor extent reduced by the presence of the σ hole and hence may be higher than in the aforementioned case. In addition to the electron density and its derived properties, the halogen–carbon bond distance opposite to the σ hole and the Raman frequency for the associated vibration emerge as alternative criteria to gauge the halogen-bond strength. We find exceptionally long C—I distances for tetra­fluoro­diiodo­benzene molecules in cocrystals with short halogen bonds and a significant red shift for their Raman vibrations.

Method for producing photonic wire bonds

A method for making optical connections with optical waveguides includes mounting the optical waveguides or a device comprising the optical waveguides, on a component carrier. A partial region of the optical waveguides is embedded in a volume of resist material. Positions of the optical waveguides to be connected are detected with reference to a coordinate system using a measuring system. Favorable, three-dimensional geometries are determined for optical waveguide structures for connecting the optical waveguides to each other at predetermined connecting locations and the optical waveguide structure geometries are converted to a machine-readable dataset. The optical waveguide geometries in the volume of the resist material are three-dimensionally structured using a direct-writing lithography device operating on the basis of the machine-readable dataset. The structured resist material is treated using physical or chemical methods to form at least one optical waveguide structure having ends connected to predetermined connecting locations of the optical waveguides.

Package-on-package assembly with wire bonds to encapsulation surface

A method of making a microelectronic package includes forming a dielectric encapsulation layer on an in-process unit having a substrate having a first surface and a second surface remote therefrom. A microelectronic element is mounted to the first surface of the substrate, and a plurality of conductive elements exposed at the first surface, at least some of which are electrically connected to the microelectronic element. Wire bonds have bases joined to the conductive elements and end surfaces remote from the bases and define an edge surface extending away between the base and the end surface. The encapsulation layer is formed to at least partially cover the first surface and portions of the wire bonds with unencapsulated portions of the wire bonds being defined by at least one of the end surface or a portion of the edge surface that is uncovered thereby.
