    Abstract: Tridentate pincer ligand supported metal complexes are formed where the complex is a trianionic pincer ligand supported metal-alkylidyne complex or a tetra-anionic pincer-ligand supported metallacycloalkylene complex formed by addition of an alkyne to the trianionic pincer ligand supported metal-alkylidyne complex. The tridentate pincer ligand supported metal complex that includes a group 5-7 transition metal and an OCO trianionic pincer ligand or an alkyne adduct thereof and methods of preparing the complexes are disclosed. The use of the tridentate pincer ligand supported metal complex for the polymerization of alkynes is disclosed, where high molecular weight poly(alkyne)s can be formed in high yield. The poly(alkyne) can be a macrocyclic polymer.
