In order to search for new anionic architectures and develop useful organic–inorganic hybrid materials in halometallate systems, two new crystalline organic–inorganic hybrid compounds have been prepared, i.e. catena ‐poly[triethyl(2‐hydroxyethyl)azanium [[bromidocadmate(II)]‐di‐μ‐bromido]], {(C 8 H 20 NO)[CdBr 3 ]} n , (1), and catena ‐poly[triethyl(2‐hydroxyethyl)azanium [[bromidomercurate(II)]‐di‐μ‐bromido]], {(C 8 H 20 NO)[HgBr 3 ]} n , (2), and the structures determined by X‐ray diffraction analysis. The compounds are isostructural, crystallizing in the space group P 2 1 / n . The metal centres are five‐coordinated by bromide anions, giving a slightly distorted trigonal–bipyramidal geometry. The crystal structures consist of one‐dimensional edge‐sharing chains of M Br 5 trigonal bipyramids, between which triethylcholine counter‐cations are intercalated. O—H...Br hydrogen‐bonding interactions are present between the cations and anions.
