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.
利用含有桥连吡唑单元和附加(新戊基)氨基吡啶基的双核配体,实现了末端羟基金属配合物 M(II)(2)(M(II)=Co,Mn)的合成。对配合物的结构研究表明,M(II)-OH 单元处于顺式构型,使羟基金属配体位置非常接近(约 3 Å 分离),这可能是水氧化的前提条件。
