STRUCTURE OF A NEW BINUCLEAR COMPLEX OF TUNGSTEN [W <sub>2</sub>S <sub>4</sub>Cl <sub>2</sub>(dppe) <sub>2</sub>]×2CH <sub>3</sub>CN
In the reaction of (Et 4N) 2[W 2S 4Cl 4] with 1,2-bis(diphenylphosphino)ethane in acetonitrile a new binuclear complex of tungsten(V) [W 2S 4Cl 2(dppe) 2]×2CH 3CN is obtained. Its crystal structure is solved in the triclinic space group P-1 with the following unit cell parameters a = 10.1202(16) Å, b = 11.758(2) Å, c = 12.648(2) Å, α = 104.324(5)°, β = 106.469(5)°, γ = 97.587(5)°, V = 1364.9(4) Å 3, Z = 1, with the final refinement parameters R 1 = 0.0545, wR 2 = 0.1053. The work describes the synthesis, crystal structure, and Raman spectrum of the [W 2S 4Cl 2(dppe) 2]×2CH 3CN complex.
