The synthesis and characterization of the isomeric ruthenium complexes with the general formula and [Ru(trpy)(qc)X] (trpy is 2,2':6',2″-terpyridine, qc is 8-quinolinecarboxylate, and , X = Cl, = 0; and , X=OH, = 1) with respect to the relative disposition of the carboxylate and X ligands are reported. For comparison purposes, another set of ruthenium complexes with general formula and [Ru(trpy)(pic)(OH)] (pic is 2-picolinate (-, -)) have been prepared. The complexes with a qc ligand show a more distorted geometry compared to the complexes with a pic ligand.

Water oxidation is the key half reaction in artificial photosynthesis. An absence of detailed mechanistic insight impedes design of new catalysts that are more reactive and more robust. A proposed paradigm leading to enhanced reactivity is the existence of oxyl radical intermediates capable of rapid water activation, but there is a dearth of experimental validation.
