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 SALPD^2- [N,N'-bis(salicylidene)-1,3-propanediaminate] and acetate ligands. The central Cd^II ion is in a distorted octahedral coordination environment formed by four O atoms from two SALPD^2- ligands in the equatorial plane and two O atoms of two symmetry-related acetate ligands in the axial positions. The symmetry-related Ni^II ions are in slightly distorted octahedral environments, coordinated by two O and two N atoms from tetradendate SALPD^2- 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 NiCd distance is 3.1482 (15) Å. The crystal structure is stabilized by weak C-HO hydrogen bonds.
