In a rare finding, an Indian grey wolf (Canis lupus pallipes) was documented for the first time in Cauvery Wildlife Sanctuary in Chamarajanagara district. The wild animal was documented by Sanjay Gubbi of Nature Conservation Foundation, and his team, while camera trapping for studying leopards.

Only those Indian nationals who show no signs of contracting the coronavirus infection and have been stranded in the US due to the lockdown are allowed to board the first repatriation flight of Air India from San Francisco to Mumbai and Hyderabad on Saturday. Over 10,000 registrations were recieved. People travelling under compelling circumstances were prioritised.

In this post, we’ll take a closer look at what happens if there’s an unencoded ampersand that’s not part of a character reference in your HTML code. Is it valid? Is it invalid? And what do “ambiguous ampersands” have to do with all this?

Sara Ali Khan shared a beautiful picture of Amrita Singh and Rukhsana Sultana holding her newborn self

Sanjay Raut took to his official Twitter handle on Sunday to let know his suggestion via a post regarding the situation.

Picture shows Sania and her son, wearing nightsuits all cuddled up in bed. Izhaan has a sweet smile on his face that can brighten anyone's day.

The crystal structure of title salt, C22H46N42+·2NO3−·2H2O, has been determined using synchrotron radiation at 220 K. The structure determination reveals that protonation has occurred at diagonally opposite amine N atoms. The asymmetric unit contains half a centrosymmetric dication, one nitrate anion and one water mol­ecule. The mol­ecular dication, C22H46N42+, together with the nitrate anion and hydrate water mol­ecule are involved in an extensive range of hydrogen bonds. The mol­ecule is stabilized, as is the conformation of the dication, by forming inter­molecular N—H⋯O, O—H⋯O, together with intra­molecular N—H⋯N hydrogen bonds.

Each central platinum(II) atom in the crystal structures of chlorido­[dihy­droxybis­(1-imino­eth­oxy)arsanido-κ3N,As,N']platinum(II), [Pt(C4H10AsN2O4)Cl] (1), and of chlorido­[dihy­droxybis­(1-imino­prop­oxy)arsanido-κ3N,As,N']platinum(II), [Pt(C6H14AsN2O4)Cl] (2), is coordinated by two nitro­gen donor atoms, a chlorido ligand and to arsenic, which, in turn, is coordinated by two oxygen donor ligands, two hydroxyl ligands and the platinum(II) atom. The square-planar and trigonal–bipyramidal coordination environments around platinum and arsenic, respectively, are significantly distorted with the largest outliers being 173.90 (13) and 106.98 (14)° for platinum and arsenic in (1), and 173.20 (14)° and 94.20 (9)° for (2), respectively. One intra­molecular and four classical inter­molecular hydrogen-bonding inter­actions are observed in the crystal structure of (1), which give rise to an infinite three-dimensional network. A similar situation (one intra­molecular and four classical inter­molecular hydrogen-bonding inter­actions) is observed in the crystal structure of (2). Various π-inter­actions are present in (1) between the platinum(II) atom and the centroid of one of the five-membered rings formed by Pt, As, C, N, O with a distance of 3.7225 (7) Å, and between the centroids of five-membered (Pt, As, C, N, O) rings of neighbouring mol­ecules with distances of 3.7456 (4) and 3.7960 (6) Å. Likewise, weak π-inter­actions are observed in (2) between the platinum(II) atom and the centroid of one of the five-membered rings formed by Pt, As, C, N, O with a distance of 3.8213 (2) Å, as well as between the Cl atom and the centroid of a symmetry-related five-membered ring with a distance of 3.8252 (12) Å. Differences between (2) and the reported polymorph [Miodragović et al. (2013). Angew. Chem. Int. Ed. 52, 10749–10752] are discussed.
