RÉSUMÉ
In the hydrated title salt, (C10H8NO2)2[SnCl6]·2H2O, the tin(IV) atom is located about a center of inversion. In the crystal structure, the organic cation, the octa-hedral inorganic anion and the water mol-ecule of crystallization inter-act through O-Hâ¯O, N-Hâ¯O and O-Hâ¯Cl hydrogen bonds, supplemented by weak π-π stacking between neighboring cations, and C-Clâ¯π inter-actions.
RÉSUMÉ
The title hybrid compound, (C5H5N2Cl2)2[SnCl6]·2H2O, was synthesized and its structure was identified by single-crystal X-ray diffraction. The structure is non-polymeric (0D) in terms of containing isolated [SnCl6]2- polyhedra. The special position (0,0,0) of the SnIV atom in the crystal structure gives rise to a stacking structure with alternating cationic and anionic layers parallel to (001). The water mol-ecules are inter-calated between these layers, which are linked by cation-anion hydrogen bonds and dominant non-covalent inter-actions. The stability of the three-dimensional network for this compound is also discussed.
RÉSUMÉ
In the title hydrated mol-ecular salt {systematic name: 4-[amino-(iminium-yl)meth-yl]pyridin-1-ium hexa-chlorido-stannate(IV) dihydrate}, (C6H9N3)[SnCl6]·2H2O, the tin atom lies on a crystallographic inversion centre and the organic cation shows whole-mol-ecule disorder. Numerous N-Hâ¯O, N-Hâ¯Cl and O-Hâ¯Cl hydrogen bonds link the components in the crystal.
RÉSUMÉ
In the title mol-ecular salt, (C5H7N2)2[SnCl6], the cation is protonated at the pyridine N atom and the complete dianion is generated by a crystallographic centre of symmetry. In the crystal, N-Hâ¯Cl hydrogen bonds link the components into a three-dimensional network built up from the stacking of alternate cationic and anionic layers. The nature of the inter-molecular inter-actions has been analysed in terms of the Hirshfeld surfaces of the cations and the anions. The thermal behaviour and the Raman spectrum of the title compound are reported.
