Abstract: The title binuclear compound, [W₂Cl₆(NO)₂(C₁₀H₂₂P₂)₃], contains two W atoms which are bridged by a bis(diethylphosphino)ethane (depe) ligand. The seven-coordinated tungsten(II) centres display distorted pentagonal-bipyramidal geometries with trans nitrosyl and chloride ligands. The title molecule lies on a crystallographic inversion centre. The ethane group of the non-bridging depe ligand is positionally disordered, with site-occupancy factors of 0.63 and 0.37. In the crystal structure, the binuclear molecules are linked by weak intermolecular C-HO and C-HCl interactions. In addition, weak intramolecular C-HCl interactions are also present.
