Experimental results (recent IR, DFT calculations and modern multinuclear NMR measurements on Rh-containing clusters, together with earlier VT multinuclear NMR measurements) show that the use of the Ligand Polyhedral Model (LPM) to provide a general

The progressive addition of anhydrous pyridine, (py), to a solution of [Rh(4)(CO)(12)] in CH(2)Cl(2) under CO, even at low temperature, results in immediate disproportionation to give cis-[Rh(CO)(2)py(2)][Rh(5)(CO)(15)]; further addition of pyridine

Both Rh4(CO)12 and Rh6(CO)16 exhibit CO-fluxionality and modern, variable temperature, NMR methods allow the unambiguous assignment of the three terminal CO resonances and, for Rh4(CO)12, show that the mechanism of CO-fluxionality, which has been con

Progressive displacement of acac from [Pd(acac)2] occurs on reaction with different tetramic acids (HL � /Hata, Habta) to give [Pd(acac)(h 2 -L)] and [Pd(h 2 -L)2] but, when HL� /Haceta, only [Pd(acac)(h 2 -L)] is formed, even when the ratio of P
