Copper(II) acetate complexes, [CuLm(OAc)2]n (L = HNPPh3), stable in the solid state either as a dimer (m = 1, n = 2) or a monomer (m = 2, n = 1).

Abstract

The synthesis and X-ray structures of two novel copper(II) phosphinimine acetate complexes, monomeric Cu(HNPPh3)2(OAc)2 and dimeric [Cu(HNPPh3)(OAc)2]2, are described. Intramolecular hydrogen bonding between acetate ligands and the imino hydrogen stabilizes Cu(HNPPh3)2(OAc)2, whereas the copper(II) tetraacetato core of [Cu(HNPPh3)(OAc)2]2 possesses neither intra- nor intermolecular hydrogen bonding.
