catena-Poly[[[bis-(acetato-κ(2)O,O')aqua-cadmium]-μ-[(pyridin-3-yl)(pyridin-4-yl)methanone]-κ(2)N:N'] dihydrate].
In the title complex, {[Cd(CH(3)COO)(2)(C(11)H(8)N(2)O)(H(2)O)]·2H(2)O}(n), the Cd(II) ion adopts an O(5)N(2) penta-gonal-bipyramidal coordination geometry with four acetate O atoms and one water O atom at the equatorial sites and two pyridine N atoms at the axial sites. The (pyridin-3-yl)(pyridin-4-yl)methanone ligand acts in a μ(2)-bridging mode, linking the metal atoms, leading to an infinite chain along [-110]. O-H⋯O hydrogen bonds involving the lattice water mol-ecules connect these chains into a three-dimensional network.
