Abstract

The crystal structure of the title compound, [Ni2Cd(C17H16N2O2)2(C2H3O2)2(C3H7NO)2], contains discrete centrosymmetric hetero-trinuclear mol­ecules in which Ni/Cd atom pairs are triply bridged via O atoms from the SALPD2− [N,N′-bis­(salicyl­idene)-1,3-propane­diaminate] and acetate ligands. The central CdII ion is in a distorted octa­hedral coordination environment formed by four O atoms from two SALPD2− ligands in the equatorial plane and two O atoms of two symmetry-related acetate ligands in the axial positions. The symmetry-related NiII ions are in slightly distorted octa­hedral environments, coordinated by two O and two N atoms from tetra­dendate SALPD2− ligands in the equatorial plane, while the axial positions are occupied by O atoms from a dimethyl­formamide and an acetate ligand. This results in the formation of three edge-shared octa­hedra in which the Ni⋯Cd distance is 3.1482 (15) Å. The crystal structure is stabilized by weak C—H⋯O hydrogen bonds.
