The magnitude of the interaction energies and Pt-3-M distances indicate a substantial covalent character of the bond, the latter being confirmed by orbital diagrams. The chemical bond is sensitive to electron correlation effects. In addition, the Fukui index of nucleophilic attack and electrophilicity index on the metal were used to explore possible sites where chemical reactivity may play a role.
