Bis{(Mu-Nitrato)[Mu-Bis(Salicylidene)-1,3-Propanediaminato] Copper(II)}Zinc(II)

Abstract

The title compound, [Zn{Cu(NO3)(C17H16N2O2)}(2)], has the central Zn2+ ion located on an inversion centre, with four bridging O atoms from two N,N'-bis(salicylidene)-1,3-propanediaminate (SALPD(2-)) ligands and one O atom from each bridging nitrate group as nearest neighbours. This arrangement constitutes a distorted octahedral coordination around the Zn2+ ion. The inversion-related terminal Cu2+ ions have irregular square-pyramidal coordinations involving two. O and two N atoms of a SALPD(2-) ligand and one O atom from a nitrate group in the axial position. The Zn-Cu pairs are triple bridged by the SALPD(2-) O atoms and by the O-N-O atoms of the nitrate groups. The Zn Cu bridging distance is 3.0017 (6) Angstrom.
