Crystal structure and Hirshfeld surface analysis of tri-chlorido-(1,10-phenanthroline-κ ,')phenyltin(IV).

The title compound, [Sn(CH)Cl(CHN)], which was obtained by the reaction between 1,10-phenanthroline and phenyl-tin trichloride in methanol, exhibits intra-molecular hydrogen-bonding inter-actions involving the chlorine and hydrogen atoms. Crystal cohesion is ensured by inter-molecular C-H⋯Cl hydrogen bonds, as well as -⋯π and π-stacking inter-actions involving three different aromatic rings with centroid-centroid distances of 3.6605 (13), 3.

Bis(2-carb-oxy-quinolinium) hexa-chlorido-stan-nate(IV) dihydrate.

In the hydrated title salt, (CHNO)[SnCl]·2HO, 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-H⋯O, N-H⋯O and O-H⋯Cl hydrogen bonds, supplemented by weak π-π stacking between neighboring cations, and C-Cl⋯π inter-actions.
