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)
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.
