Poly[[bis(1H-benzimidazole-kappaN3)cadmium(II)]-mu-aqua-mu-succinato-kappa2O1:O4].

The title compound, Cd(C(4)H(4)O(4))(C(7)H(6)N(2))(2)(H(2)O), is a three-dimensional polymeric complex. The Cd(II) atom is located on an inversion centre and assumes an elongated octahedral coordination geometry, with a long Cd-O distance of 2.5381 (5) A to the coordinated bridging water molecule. The succinate dianion, located on another inversion centre, bridges adjacent Cd atoms to form succinate-bridged polymeric chains. The coordinated water molecule is located on a twofold axis and links adjacent succinate-bridged chains to form a water-bridged polymeric chain.
