catena-Poly[cyclohexylammonium [cadmate(II)-tri-mu-bromido]]

The title compound, {(C6H14N)[CdBr3]}(n), self-assembles into a layered structure consisting of alternating organic and inorganic layers, with the two Cd atoms on inversion centres. In the inorganic layer, octahedral CdBr6 units share faces to form a one-dimensional perhalometallate chain, which interacts with the ammonium groups of the cations through hydrogen bonds, forming a two-dimensional hydrogen-bonded sheet.
