Bridging Ligand - Polyfunctional Ligands

Polyfunctional Ligands

Polyfunctional ligands can attach to metals in many ways and thus can bridge metals in diverse ways, including sharing of one atom or using several atoms. Examples of such polyatomic ligands are the oxoanions CO₃2− and the related Carboxylate, PO₄3−, and the polyoxometallates. Several organophosphorus ligands have been developed that bridge pairs of metals, a well-known example being Ph₂PCH₂PPh₂.
