Ng. Connelly et al., REDOX-INDUCED KAPPA(2)-KAPPA(3) ISOMERIZATION IN RHODIUM HYDROTRIS(3,5-DIMETHYLPYRAZOLYL)BORATE CHEMISTRY - THE STABILIZATION OF SQUARE-PYRAMIDAL RHODIUM(II), Chemical communications, (19), 1996, pp. 2289-2290
One-electron. oxidation of the square-planar, 16-electron complex [Rh(
CO)(PPh(3)>(kappa(2)-Tp')] with [FeCp(2)][PF6] gives the square-pyrami
dal Rh-II complex [Rh(CO)(PPh(3))(kappa(3)-Tp')][PF6] in which the thi
rd pyrazolyl group of Tp' is N-bound in the axial position by a three-
electron two-centrebond (Rh-N-axial 0.13 Angstrom longer than Rh-N-bas
al).
