seven-coordinate compound MoCl4(PMe3)3 has been prepared by the room temperature reaction of MoCl4(THF)2 and PMe3. This complex is a useful starting material for the synthesis of other trimethylphosphine derivatives of molybdenum. Reduction, under different experimental conditions, affords the known complexes MoCl3(PMe3)3, MoCl3(PMe3)4, cis-Mo(N2)2(PMe3)4 and trans-Mo(C2H4)2(PMe3)4. Interaction with H2O,
