Abstract A nickel(II) complex containing both dithiolato and phosphine ligands, Ni 2 (PPh 3 ) 2 (edt) 2 (edt = SCH 2 CH 2 S 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) Å, α = 102.84(2), β = 96.49 (2), γ = 82.56(3); V = 1906.8 Å 3 ; D c = 1.439 g·cm −3 for Z = 2; the final conventional 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 Å, 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 Å and Ni—P bond 2.188 Å. The UV‐Vis and 1 H NMR spectra have also been recorded.
