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 <sub>4</sub>N) <sub>2</sub>[W <sub>2</sub>S <sub>4</sub>Cl <sub>4</sub>] with 1,2-bis(diphenylphosphino)ethane in acetonitrile a new binuclear complex of tungsten(V) [W <sub>2</sub>S <sub>4</sub>Cl <sub>2</sub>(dppe) <sub>2</sub>]×2CH <sub>3</sub>CN is obtained. Its crystal structure is solved in the triclinic space group <i>P</i>-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)°, <i>V</i> = 1364.9(4) Å <sup>3</sup>, <i>Z</i> = 1, with the final refinement parameters <i>R</i> <sub>1</sub> = 0.0545, <i>wR</i> <sub>2</sub> = 0.1053. The work describes the synthesis, crystal structure, and Raman spectrum of the [W <sub>2</sub>S <sub>4</sub>Cl <sub>2</sub>(dppe) <sub>2</sub>]×2CH <sub>3</sub>CN complex.
