[Cu(H(2)dppd)(eta(1)-OClO3)]ClO4: The first crystallographically characterized phosphine complex of copper(II) {H(2)dppd=N,N'-bis[2-(diphenylphosphino)phenyl]propane-1,3-diamine}

The title complex 2, easily obtained by controlled potential oxidation of the copper(I) precursor [Cu(H2dppd)]BF4 1, in perchlorate medium, crystallizes as a C6H6 monosolvate from dichloroethane-benzene, (2a), or as a CH2Cl2 hemisolvate from dichloromethane-toluene (2b), to give dark-red crystals which have been structurally characterized by X-ray crystallography.
