Abstract	SummaryThe addition of NPm (diphenylaminodiphenylphosphinomethane) to CuI or the addition of KI to (NPm)2CuNO3 leads to the same P-bonded CuI complex, (NPm)2CuI, presenting a trigonal geometry around the Cu atom. The reaction of this new complex (or of its chloro analogue) with a CuII salt yields dinuclear species of general formula [(NPm)Cu(μ-X)2Cu(NPm)] (X = Cl or I). X-ray analysis of these complexes show that they are isostructural and retain the trigonal geometry around the metal atom. The Cu···Cu distances are 2.775(1)Å for X = Cl and 2.642(1) Å for X = I. The Cu-(μ-X)-Cu angle is more acute for the iodide [61.48(3)°] than for the chloride [74.17(8)°] complex. These values are discussed in terms of Cu···Cu interactions induced by the electron donor ability of X and the bulk of the phosphine L.
