Abstract

The solution structures and dynamic behaviour of [Rh6(CO)14(μ-PX)] [PX = diphenyl(2-pyridyl)phosphine, (PN); diphenyl(2-thienyl)phosphine, (PS); diphenyl(vinyl)phosphine, (PV)] have been studied by multinuclear NMR and the X-ray structure of [Rh6(CO)14(μ,κ3-PV)] is reported. In solution, the above clusters undergo a variety of localised CO-exchanges and the mechanisms of these are discussed. The PV ligand in [Rh6(CO)14(μ,κ3-PV)] is hemilabile and exhibits facile exchange/reorientation of the vinyl group.
