Synthesis of some pentanuclear platinum clusters [Pt5(CO)6(L)4]. The X-ray structure of [Pt5(μ-CO)5(CO)(PCy3)4]

Some pentanuclear platinum clusters [Pt5(CO)(μ-CO)5(PR3)4] can be conveniently prepared using two different synthetic methods. The first complete NMR characterization of these complexes has been achieved and showed that these Pt5 clusters exhibit similar stereochemistries in solution and in the solid state.
