The crystal structure of a DMSO monosolvate monohydrate of a previously unknown monosodium salt of the industrial inter­mediate Pigment Red 52 (P.R.52) with the formula Na+[C18H12ClN2O6S]·H2O·C2H6OS. The compound was obtained by in-house synthesis. The crystals have triclinic symmetry at 173 K. The crystal structure is built up by Na—O chains, which arrange the anions in polar/non-polar double layers.

The superionic conducting Na Super-Ionic CONducting-type (NaSICON-type) material Ag3Sc2(PO4)3 was studied by single-crystal X-ray diffraction between 100 and 520 K. Two phase transitions were found, at 177 and 291 K. Full structural characterization of the three polymorphs is given for the first time.

The title compound represents a ionic mixed-valent tin(II)–tin(IV) compound with the bivalent tin atom as central atom of the cation and the tetra­valent tin atom as central atom of the anion. Regarding the first and second coordination sphere, the bivalent tin atom is fourfold, seesaw and fivefold, trapezoid–pyramidal coordinated while the tetra­valent tin atom exhibits an octa­hedral coordination.

The new organoarsenate salt o-anisidinium di­hydro­arsenate possesses a layered supra­molecular architecture in the crystal. Hydrogen bonds and H...H contacts play dominant roles in the crystal structure. An analysis of the electronic structure and mol­ecular modelling using charge distribution confirms the good electrophilic reactivity.

The crystal structure of a valinomycin complex with an encapsulated [Mg(H2O)6]2+ ion as an independent structural unit is described. The new cation-binding mode exhibited by valinomycin, a cyclic dodecadepsipeptide, occurs via hydrogen bonds from the coordinated water mol­ecules of the hexa­hydrate cation, instead of via direct links to the cation. The inter­action of the [Mg(H2O)6]2+ ion with the cyclic polypeptide has important implications for the study of metal binding with biological models under physiological (aqueous) conditions.

The structure of 1-methyl-2-(prop-2-en-1-ylsulfan­yl)-1H-imidazol-3-ium bromide, C7H11N2S+·Br, has monoclinic (P21/c) symmetry. In the crystal, the components are linked by N—H...Br and C—H...Br hydrogen bonds. The crystal structure of the title compound undeniably proves that methimazole reacts through the thione tautomer, rather than the thiol tautomer in this system.
