AbstractMn(bzimpy)(2) (1) [ bzimpy = 2, 6-bis (benzimidazol-2-yl) pyridine], a mononuclear manganese(H) complex, was synthesized by the reaction of Mn (OOCMe)(2) with bzimpy in absolute ethanol. The complex was structurally characterized by elemental analysis, cyclic voltammetry, and X-ray crystallography. In the complex, the manganese-nitrogen distances were different, and the geometry and the metal ion environment showed the distortion. The cyclic voltammetric measurements have been performed to assess its redox characteristics. The presence of oxidation wave at + 0.62 V and + 0.81 V vs. SCE or + 0.8 V and + 1.0 V vs. NHE suggested that this complex could catalyze the oxidation of water, therefore, simulate the water-oxidizing complex (WOC) of photosystem H (PS H). The measurements of photoreduction of 2, 6-dichlorophenolindophenol (DCPIP), and oxygen evolution in the manganese-depleted and the complex 1-reconstituted PS II preparations just support our conjecture.
