derivative MoOCl2(PMe3)3 have been obtained by an oxygen-atom abstraction reaction between MoCl4(thf)2 and equimolar amounts of water in the presence of PMe3. Methatesis with KX(X = NCO, NCS) yields MoOX2(PMe3)3 and with NaS2CNEt2, MoO(S2CNEt2)2(PMe3). The latter complex readily loses PMe3 to give MoO(S2CNEt2)2 from which it can be prepared by addition of the phosphine ligand. Reaction of the blue purple
