Implication

Demonstrates the transformation of tetranuclear complexes into trinuclear forms, suggesting implications for molybdoenzyme functions.

Abstract

Many molybdoenzymes contain two molybdopterin (MPT) ligands but the mechanism for the transformation of mono(MPT)Mo to bis(MPT)Mo is lacking. Using a catecholate-based system, we demonstrate that [MoVI(Lcat)O3]2- forms a dimeric...
