In the centrosymmetric title compound, [CdNi2(C17H16N2O2)(2)(HCOO) 2(H2O)(2)]center dot 2H(2)O, The Ni II cation is chelated by a 2,2'-[propane-1,3-diylbis(nitrilomethanylylidene)] diphenolate (salpn) anion, and further coordinated by a formate anion and a water molecule in a distorted NiN2O4 octahedral geometry. The Cd-II cation, located on an inversion center, is coordinated by four deprotonated hydroxy groups from two salpn anions and two carboxylate O atoms from formate anions in a distorted octahedral geometry. Both formate and salpn anions bridge the Cd and Ni cations, forming a trinuclear complex. Within the salpn anion, the benzene rings are twisted to each other at a dihedral angle of 61.46 (18)degrees. Intermolecular O-H center dot center dot center dot O hydrogen bonding is present in the crystal structure. The lattice water molecule is disorder over two positions with an occupancy ratio of 0.75:0.25.
