{[mu-Bis(salicylidene)-1,3-propane-diaminato](3-methylpyridine)copper(II)}-diiodozinc(II)

The title complex, [CuZnI2(C17H16N2O2)(C6H7N), consists of a doubly oxygen- bridged heteronuclear dimeric complex. The Cu atom has a distorted square-p yramidal environment involving two O atoms and two N atoms of the bis(salic ylidene)-l,3-propanediaminate (SALPD(2)-) ligand, and an N atom of the 3-me thylpyridine group. The Cu-O distances in the coordination plane are 1.973 (3) and 1.974(2)Angstrom, and the average Cu-N distance is 2.088 (4) Angstr om. In the bridging plane, the Cu-O-Zn, O-Zn-O, Zn-O-Cu and O-Cu-O angles a re 102.5(1), 76.7(1), 102.7(1) and 77.9(1)degrees, respectively. The dihedr al angle between the coordination plane around the Cu atom and the 3-melhyl pyridine group is 88.4(1)degrees. The Cu Zn distance is 3.1013 (7) Angstrom .
