Abstract

?2 -Vinyl complexes [MCl{?2 -C(CF3)C(CF3)L} (CF3CCCF3)(?5 -C5H5)] (M = Mo, W: L = tertiary phosphine or phosphite or pyridine) have been shown by NMR and X-ray diffraction studies to exist in two distinct isomeric forms which exhibit (a) different orientations of the ?2 -vinyl ligand (b) different configurations at the asymmetric carbon atom of the ?2 -vinyl ligand: variable temperature NMR studies reveal fluxional behaviour thought to involve reversible inversion of configuration at this carbon atom. © 1983.
