Transformation of the cluster Pt3(µ-CO)3(PPh3)4 into Pt5(µ-CO)5(CO)(PPh3)4 upon impregnation onto inorganic supports
Abstract
The impregnation of organic solutions of Pt3(µ-CO)3(PPh3)4 onto inorganic supports used for catalysis or chromatography has been shown to produce Pt5(µ-CO)5(PPh3)4, depending upon the nature of the support, its pre-treatment, and the solvent used; these observations are relevant to the preparation of cluster-derived catalysts.
