Di-μ-nicotinamide-κ(2) N (1):O;κ(2) O:N (1)-bis­[aqua­bis­(3-chloro­benzoato-κ(2) O,O′)cadmium]

In the centrosymmetric dinuclear title compound, [Cd(2)(C(7)H(4)ClO(2))(4)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Cd(II) atom is coord­inated by one N atom from one bridging nicotinamide ligand and one O atom from another symmetry-related bridging nicotinamide ligand, four O atoms from two 3-chloro­benzoate ligands and one water mol­ecule in an irregular geometry. The dihedral angles between the carboxyl­ate groups and the adjacent benzene rings are 6.98 (12) and 2.42 (13)°, while the benzene rings are oriented at a dihedral angle of 4.33 (6)°. Inter­molecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. π–π inter­actions, indicated by short centroid–centroid distances [3.892 (1) Å between the pyridine rings and 3.683 (1) Å between the benzene rings] further stabilize the structure.
