Poly[[{μ(2)-3-[(1H-benzimidazol-1-yl)meth-yl]benzoato}cadmium(II)] 0.1-hydrate].

In the title polymeric compound, {[Cd(C(15)H(11)N(2)O(2))(2)]·0.1H(2)O}(n), the Cd(II) atom is coordinated by four carboxyl-ate O atoms and two benzimidazole N atoms from four benzimidazolylmethyl-benzoate anions in a distorted octa-hedral geometry. Each anion bridges two Cd atoms through the terminal carboxyl-ate group and an imidazole N atom, forming polymeric complex chains running along the b axis. The uncoordinated water mol-ecule is equally disordered over two sites; occupancies were fixed as 0.5 for each disordered component. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
