title: catena-Poly[[[dibromidocadmium]-μ(2)-1,1'-(butane-1,4-di-yl)bis-(pyridinium-4-carboxyl-ate)] monohydrate].
abstract: In the title compound, {[CdBr(2)(C(16)H(16)N(2)O(4))]·H(2)O}(n), the Cd(II) ion is six-coordinated by a Br(2)O(4) donor set, with four O atoms from two bridging 1,1'-(butane-1,4-di-yl)bis-(pyridinium-4-carboxyl-ate) ligands. The ligands link the Cd(II) ions into a zigzag chain extending along [0[Formula: see text]1]. O-H⋯O and O-H⋯Br hydrogen bonds involving the uncoordinated water mol-ecules connect the chains.
