A nickel(Ⅱ) complex containing both dithiolato and phosphine ligands, Ni_2(PPh_3)_2(edt)_2(edt = SCH_2CH_2S~(2-)), has been prepared and characterized by X-ray diffration. The complex crystallizesin the triclinic system, space group P-1, with a = 10.693(3), b = 17.457 (6), c = 10.606 (3)A, α=102.84(2), β = 96.49 (2), γ = 82.56(3)°; V = 1906.8 A~3; D_c = 1.439g.cm~(-3) for Z=2; the final con-ventional R was 0.052 based on 3338 observed reflections. Nickel atoms are linked by two sulfuratoms from two edt ligands with the Ni--Ni distance of 2.893 A, and each Ni atom is coordinatedby one phosphorus atom and three sulfur atoms with a square-planar geometry, where the average:length of Ni--S bond is 2.180 A and Ni--P bond 2.188 A. The UV-Vis and ~1H NMR spectra havealso been recorded.
