Abstract

The Cu(I) complexes, (Ph3P)(2)CuL (L = [S2PMe2](-), [OSPR2](-) (R = Me, Ph), [(XPR2)(YPR'(2))N](-) (X, Y, R, R' = O, O, Ph, Ph; O, S, Ph, Ph; O, S, OEt, Ph; S, S, Me, Me)) and Cu(II) complexes, CuL2 (L = [(XPR2)(YPR'(2))N](-) (X, Y, R, R' = O, O, Ph, Ph; O, S, Ph, Ph)), have been prepared. The Cu(I) derivatives were characterized by multinuclear NMR spectroscopy and in two cases by X-ray crystallography. (Ph3P)(2)Cu[S2PMe2] (1) crystallizes in the orthorhombic space group P2(1)2(1)2(1) (No. 19) with cell parameters a = 9.782(2), b = 17.808(4), c = 20.216(4) Angstrom, V = 3521(6) Angstrom (3) and Z = 4, and (Ph3P)(2)Cu[(OPPh2)(2)N] (4) in the triclinic space group P (1) over bar (No. 2) with cell parameters a = 9.8079(2), b = 12.9141(3), c = 22.5666(5) Angstrom, alpha = 75.714(2), beta = 79.465(2), gamma = 68.2770(8)degrees, V = 2559.9(1) Angstrom (3) and Z = 2. In both cases the phosphorusligands are bidentate, thus resulting in monomeric molecules that contain tetrahedral CuP2S2 and CuP2O2 cores. The molecular structures of two of the Cu(II) derivatives were also determined. Cu[(OPPh2)(2)N](2) (8) and Cu[(OPPh2)(SPPh2)N](2) (9) crystallize in the triclinic space groupP (1)over bar (No. 2) with cell parameters a = 8.887(2), b = 10.739(2), c = 12.477(3) Angstrom, alpha = 77.61(3), beta = 76.15(5), gamma = 79.46(3)degrees,V = 1118.3(4) Angstrom (3) and Z = 1 for 8, and a = 9.626(2), b = 14.151(3), c = 24.752(5) Angstrom, alpha = 88.23(3), beta = 79.93(3), gamma = 89.77(3)degrees, V = 3181(1) Angstrom (3) and Z = 3 for 9. The moleculeof Cu[(OPPh2)(2)N](2) (8) has a planar CuO4 core, while in Cu[(OPPh2)(SPPh2)N](2) (9) both planar and tetrahedral copper cores are observed in a ratio of 1:2.
