Abstract: In the title compound, [Cd₂Cl₄(C₁₁H₁₀N₂O₂)₂]·3H₂O, each metal atom is coordinated by an N,O,N'-chelated di-2-pyridylmethanediol ligand, two bridging chloride ligands and one terminal chloride ligand in a distorted octahedral geometry. Two isomers of centrosymmetric dinuclear complexes, and , are observed; the asymmetric unit contains two half-molecules of the complex and three water molecules. In the isomer, the CdCd distance and O-Cd-Cl_terminal angle are 3.8048 (7) Å and 160.09 (5)°, respectively. In the isomer, the same geometric parameters are 3.7281 (7) Å and 88.84 (6)°, respectively.
