Abstract

In the title complex, {[Cd(CH3COO)2(C11H8N2O)(H2O)]·2H2O}n, the CdII ion adopts an O5N2 penta­gonal–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 μ2-bridging mode, linking the metal atoms, leading to an infinite chain along [-110]. O—H⋯O hydrogen bonds involving the lattice water mol­ecules connect these chains into a three-dimensional network
