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, OE t, 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 th e 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) a nd 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 phosphor usligands are bidentate, thus resulting in monomeric molecules that contain tetrahedral CuP2S2 and CuP2O2 cores. The molecular structures of two of th e Cu(II) derivatives were also determined. Cu[(OPPh2)(2)N](2) (8) and Cu[(O PPh2)(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) An gstrom, 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)degree s, 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 pl anar and tetrahedral copper cores are observed in a ratio of 1:2.
