Abstract
The dynamic motion that the carbonyls [Co2(CO)8], [Fe3(CO)12], and [Co4(CO)12] undergo in the solid and solution has been examined. Evidence is offered to suggest that the fluxional behaviour and the isomerisation the molecules undergo may be best understood in terms of the polyhedral model in which the metal unit librates within the CO polyhedron. Support for this approach comes from an examination of the anisotropic displacement parameters of the metal atoms and the usefulness of this method to the understanding of molecular motion in the solid is stressed.Keywords
