A nickel(Ⅱ) complex containing both dithiolato and phosphine ligands, Ni_2.PPh_3)_2.edt)_2.(edt = SCH_2.H_2.^(2.)), has been prepared and characterized by X-ray diffration. The complex crystallizes in 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 = ***^(-3) for Z=2. the final con- ventional R was 0.052.based on 3338 observed reflections. Nickel atoms are linked by two sulfur atoms from two edt ligands with the Ni--Ni distance of 2.893 A, and each Ni atom is coordinated by 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 have also been recorded.
