Crystal structure of catena-poly[2-bromo-ethyl-ammonium [tin(II)-tri-μ-bromido]].

In the structure of the title salt, {(C2H7BrN)[SnBr3]} n , the tin(II)atom features a strongly distorted octa-hedral environment ensured by six bromido ligands. By face-sharing, these SnBr6 coordination octa-hedra are connected into polymeric chains, which propagate along the b-axis direction. Organic cations, stabilized in a gauche conformation, inter-leave the inorganic polymeric chains. Hydrogen bonds of the type N-H⋯Br between organic cations and inorganic chains create supra-molecular layers parallel to the ab plane. These layers inter-act with each other thought weak C-H⋯Br contacts.
