Preparation and structures of dinuclear complexes containing M II-OH centers

Article abstract of DOI:10.1039/c2cc16277f

The synthesis of M^II₂ complexes (M^IICo, Mn) with terminal hydroxo ligands has been achieved utilizing a dinucleating ligand containing a bridging pyrazolate unit and appended (neopentyl) aminopyridyl groups. Structural studies on the complexes revealed that the M^II-OH units are positioned in a syn-configuration, placing the hydroxo ligands in close proximity (ca. 3 A apart), which may be a prerequisite for water oxidation.
