The structure of the title compound, [NiZnI2(C17H16-N2O 2)(C7H9N)2], consists of doubly oxygen-bridged heteronuclear dimeric complexes. The compound is of interest because of the magnetic superexchange interactions that occur between doubly oxygen-bridged metal ions. The Ni atom has an irregular octahedral environment involving two O and two N atoms from the bis(salicylidene)-1,3-propanediaminate ligand in the equatorial plane and the N atoms from the two 3,5-dimethylpyridine groups in the apical positions. The coordination around the Zn atom is distorted tetrahedral, with an average Zn-O distance of 2.001 (2) Å and an average Zn-I distance of 2.5499 (5) Å. In the bridged plane, the Ni-O1-Zn, O1-Zn-O2, Zn-O2-Ni and 02-Ni-O1 angles are 98.82 (9), 81.2 (1), 99.8 (1) and 79.6 (1) °, respectively. The Ni⋯Zn distance is 3.0753 (7) Å.
