In the title linear trinuclear compound, [Zn{Zn(CH3COO)(C17H16N2O2)}2], the central Zn2+ ion, which is located on an inversion centre, has a distorted octahedral coordination involving four bridging O atoms from two N,N′‐bis­(salicyl­idene)‐1,3‐propane­diaminate ligands in the equatorial plane and one O atom from each bridging acetate group in the axial positions. The coordination around the terminal Zn2+ ion is irregular square pyramidal, with two O and two N atoms of the ligand in the basal plane and one O atom from an acetate group in the apical position. The acetate bridges linking the central and terminal Zn2+ ions are mutually trans. The Zn⃛Zn distance is 3.0520 (8) Å. The relationship of this structure to that of [Zn{Cu(CH3COO)(C17H16N2O2)}2] is discussed.
