Bis[4-(dimethyl-amino)pyridinium] tetra-bromidocadmate(II) monohydrate

The Cd atom in the hydrated title salt, (C(7)H(11)N(2))(2)[CdBr(4)]·H(2)O, exists in an approximately tetra-hedral coordination geometry, with Br-Cd-Br angles in the range 105.52 (3)-111.50 (3)°. The cation, anion and water mol-ecule inter-act by O-H⋯Br, N-H⋯Br and N-H⋯O hydrogen bonds, forming a linear chain structure running along the a axis.
