Abstract: In the centrosymmetric dinuclear title compound, [Cd2(C7H4ClO2)4(C6H6N2O)2(H2O)2], the CdII 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. [pi]-[pi] 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.
