Abstract: The molecule of the title compound, [Ni₂Zn(C₁₇H₂₀N₂O₂)₂(C₂H₃O₂)₂(C₃H₇NO)₂], contains a linear hetero-trinuclear arrangement with a central Zn^II ion located on an inversion centre. The ZnNi pairs are triply bridged via O atoms of SALPD^2- [N,N'-bis(salicylidene)-1,3-propanediaminate] and acetate ligands. The central Zn^II ion is in a distorted octahedral coordination environment formed by four O atoms of two SALPD^2- ligands in the equatorial plane and two O atoms of two symmetry-related acetate ligands in the axial positions. The terminal Ni^II ions, related by an inversion centre, also have distorted octahedral coordination environments formed by two O and two N atoms of SALPD^2- ligands in the equatorial plane; the axial positions are occupied by O atoms of dimethylformamide and acetate ligands, which are trans with respect to the terminal Ni atoms. The crystal structure is stabilized by weak intermolecular C-HO hydrogen bonds.
