Abstract
Treatment of the λ3-cyclotriphosphazanes, cis-{EtNP(OR)}3 [R=C6H4Br-4 (L1) or C6H4Br-2 (L2)] with [Mo(CO)4(NBD)] (NBD = norbornadiene) yields the mononuclear complexes [Mo(CO)4L1] (1) and [Mo(CO)4L2] (2), which have been characterised by IR, NMR (31P and 1H) and FAB mass spectral data. The structure of 1 has been confirmed by single crystal X-ray analysis. The structural and conformational changes brought about by complexation are discussed in terms of a bonding model based on negative hyperconjugation.
