实验表明，尽管配合物具有单核性质，[Ru(Terpy)(Bpy)(OH2)](2+)对水氧化成分子氧具有很高的催化活性。而[Ru(Terpy)(Bpy)Cl](+)则完全没有活性。用分光光度法、质谱法和气相色谱分析证实了[Ru(Terpy)(Bpy)(OH2)](2+)在硝酸铈(IV)铵盐、Ce(NH4)(2)(NO3)(6)存在的强氧化条件下是稳定的。
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.
