Abstract

The mol-ecular structure of the title compound, [Mo(2)(CH(3)COO)(2)Cl(2)(C(30)H(25)NP(2))]·0.3CH(2)Cl(2)·1.7C(4)H(8)O, features an Mo-Mo dumbbell bridged by two acetate groups which are trans to each other. Perpendicular to the plane spanned by the acetate groups, the Ph(2)PN(Ph)PPh(2) ligand bridges both Mo atoms, having a P-N-P angle of 114.09 (19)°. In a trans position to the PNP ligand are two Cl atoms, one on each molybdenum centre. The Mo-Mo bond distance is 2.1161 (9) Å, within the range known for Mo-Mo quadruple bonds. The Mo complex is located on a crystallographic twofold rotation axis which runs through the N-C bond of the ligand. The site occupation factors of the disordered solvent molecules were fixed to 0.15 for dichloromethane and 0.85 for tetrahydrofuran.
