Abstract: The title compound, [ZnI₂Ni(C₁₇H₁₆N₂O₂)(C₆H₇N)₂], is a heterodinuclear zinc-nickel complex. The Ni^II ion is in a distorted octahedral coordination environment formed by two O and two N atoms from a chelating salpd^2- ligand [salpd^2-= N,N'-bis(salicylidene)-1,3-propanediamine, C₁₇H₁₆N₂O₂] in the equatorial plane and two N atoms of two methylpyridine ligands (C₆H₇N) in the axial positions. The coordination around the Zn^II ion is distorted tetrahedral, with two bridging O atoms of the chelating salpd^2- ligand and two I atoms. The average Zn-O and Zn-I distances are 1.986 (5) and 2.5327 (11) Å, respectively. The crystal structure is stabilized by weak C-HN and C-HI hydrogen bonds.
