摘要：

Experiments show that [Ru(terpy)(bpy)(OH2)](2+) is highly active as a catalyst toward oxidation of water into molecular oxygen in spite of the mononuclear character of the complex. while [Ru(terpy)(bpy)Cl](+) shows no activity at all. It is also confirmed that [Ru(terpy)(bpy)(OH2)](2+) is fairly stable under strongly oxidizing conditions in the presence of cerium(IV) ammonium nitrate, Ce(NH4)(2)(NO3)(6), which was evidenced by spectrophotometric, mass spectrometric, and gas chromatographic analysis.
