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

ABSTRACT: The synthesis of M(II)(2) complexes (M(II)=Co, 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 Å apart), which may be a prerequisite for water oxidation.
