Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.002 Å; R factor = 0.029; wR factor = 0.080; data-to-parameter ratio = 16.4.In the title salt, [(CH 3 ) 2 CH] 2 NH 2 ] + Á[C 6 H 5 PO 2 (OH)] À , the anions are linked by pairs of O-HÁ Á ÁO hydrogen bonds, forming inversion dimers. These dimers are bridged by the cations via N-HÁ Á ÁO hydrogen bonds, leading to a threedimensional structure.

The title compound, (C6H14N)2[Sn(C6H5)2Cl4], contains cyclohexylammonium cations in general positions and a stannate(IV) anion that is located on a twofold rotation axis. The SnIV atom in the complex anion is surrounded by four Cl− ligands and two trans-phenyl groups in a distorted octahedral configuration. The anions are connected with the cations through N—H⋯Cl hydrogen bonds. Every cation is involved in three N—H⋯Cl bonds to the chloride ligands of three different anions, and each chloride ligand is linked to two cations. This arrangement leads to a layered structure parallel to (010).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
