摘要
The nickel(Ⅱ) complex Ni2(PBu3n)2(tdt)2(tdt = SC7H6S2-) containing dithiolato and phosphino ligands has been prepared and characterized by X-ray diffraction. The complex crystallizes in triclinic system, space group P1, with a = 14. 423(4), b = 15. 053(3), c=10. 648(3)(?), α=93.,95(2), β=100. 31(3), γ = 84. 16(2)°; V =2259.6 (?)3; Z = 2, Dc= 1. 22 gem-3, Mr = 830. 57; μ = 11. 076cm-1, F (000) = 888. In the complex, the Nickel atoms are linked by two bridging sulfur atoms from the two tdt ligands with the Ni-Ni distance of 2. 679 (?) . and each nickel atom is four coordinated by one phosphorus and three sulfur atoms with a square-planar geometry, the average length of Ni -S bond is 2. 193(?) and that of Ni-P bond 2.186(?).
