and 31P-1H} NMR spectral data. The molecular structures of [Cu2(L1)(PPh3)2Cl2]1 and [Cu2(L3)Cl2]3 were established by single-crystal X-ray diffraction [crystal data: 1, C94H90Cl2Cu2N2P6, triclinic, space group P, a= 11.711(2), b= 18.731(3), c= 10.080(1)Å, α= 91.22(1), β= 107.45(1), γ= 78.11(1)°, Z= 1, final R factor 0.040 (R′= 0.046) for 3715 observed reflections; 3, C64H64Cl2Cu2N2P4, triclinic, space
具有N 2 P 4或N 2 As 4供体位点的三个新的双核六齿配体,即。N,N,N ',N'-四-[2-(二苯基膦基)乙基]乙烷-1,2-二胺(L 1),其a类似物(L 2)和1,3-bis bis [2-已经制备了(二苯基膦基)乙基]氨基甲基}苯(L 3)。配体与[Cu(PPh 3)3 Cl]反应,得到双核四配位铜(I)络合物[Cu 2(L 1)(PPh 3)2 Cl 2 ],[Cu 2(L 2)(PPh 3) 2 Cl 2 ]和[Cu 2(L 3)Cl 2 ]。用[Cu(NCMe) 4 ] [ClO 4 ]配体产生三坐标双核络合物[Cu 2 L] [ClO 4 ] 2(L = L 1,L 2或L 3),用NaN 3。NH 4 NCS,KOH或NaBH 4(L = L 1或L 3)通过消除高氯酸盐和X的配位得到双核四配位铜(I)配合物[Cu 2 L(X)2 ](X = N 3,NCS,OH或BH
