Abstract
The compounds [Mo(N3S2){Ph2(O)PNP(S)Ph2}2] 1 [Mo(N3S2){iPr2(O)PNP(S)iPr2}2] 2 have been synthesised by treating [MoCl3(N3S2)] with KN(PPh2S)2 or KN(PiPr2S)2. X–Ray structures of 1 and 2 have been solved. On complexation, the MoN3S2 ring remained planar, but the Mo(OPNPS)2 rings are puckered.
