Abstract

The reaction of [Mo(CO)4(nbd)](nbd = norbornadiene) with trans-[EtNP(OC6H3Me2-2,6)]3(L1) or cis-[EtNP(OCH2CF3)]3(L2) yields the mono- and di-nuclear molybdenum(0) complexes [Mo(CO)4(L1)]1 and [{Mo(CO)4(µ-L2)}2]2, respectively. They represent the first organometallic transition-metal derivatives of λ3-cyclotriphosphazanes and have been characterised by elemental analysis and IR and NMR spectroscopy and their structures confirmed by X-ray crystallography. The different co-ordination behaviour of the cis and trans isomeric forms of this type of ligand is revealed. A pyramidal geometry observed around one of the nitrogen atoms of the P3N3 ring in complex 1 is unprecedented among λ3-phosphazanes.
