Summary

The complexfac-[Mo(CO)3(NCMe)3] (preparedin situ) reacts with an equimolar amount of ICl to give the oxidised product [MoClI(CO)3(NCMe)2] (1) in high yield. Equimolar quantities of (1) and L (L=PPh3, AsPh3 or SbPh3) react to yield the iodo-bridged dimers [Mo-(μ-I)Cl(CO)3L]2 (2)–(4). The reaction of [MoClI(CO)3(NCMe)2] with two equivalents of L (L=PPh3, AsPh3 or SbPh3) yields the acetonitrile-displaced products [MoClI(CO)3L2] (5)–(7). The bidentate ligands L^L {L^L=2,2-bipyridyl (bipy), 1,10-phenanthroline (1,10-phen), CyN=CHCH=NCy, Ph2P(CH2)nPPh2 (n=1–4)} react with an equimolar quantity of (1) to give [MoClI(CO)3(L^L)] (8)–(14). The compounds have been characterised by elemental analysis and spectroscopy. Magnetic susceptibility measurements show the compounds to be diamagnetic.
