?-1,2-Bis(diethyl-phosphino)ethane-?P:P'-bis-{[1,2-bis-(diethyl-phosphino)ethane-?P,P']trichloridonitrosyl-tungsten(II)}.

ABSTRACT: The title binuclear compound, [W(2)Cl(6)(NO)(2)(C(10)H(22)P(2))(3)], contains two W atoms which are bridged by a bis-(diethyl-phosphino)-ethane (depe) ligand. The seven-coord-inated tungsten(II) centres display distorted penta-gonal-bipyramidal geometries with trans nitrosyl and chloride ligands. The title mol-ecule 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 mol-ecules are linked by weak inter-molecular C-H?O and C-H?Cl inter-actions. In addition, weak intra-molecular C-H?Cl inter-actions are also present.
