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-H...O and C-H...Cl interactions. In addition, weak intramolecular C-H...Cl interactions are also present.
