[Ru（tmtacn）（R（2）bpy）（OH 2）]（2+）（tmtacn = 1，4，7-三甲基-1，4，7-三氮杂环壬烷; R（2）bpy = 4，4 '-二取代-2，2'-联吡啶，R = H，Me，和OMe）与tmtacn以面键方式连接，具有放氧催化活性.研究还发现，R（2）bpy的强给电子性使其具有较高的放氧活性。
[Ru(tmtacn)(R(2)bpy)(OH2)](2+) (tmtacn = 1,4,7-trimethyl-1,4,7-triazacyclononane; R(2)bpy = 4,4'-disubstituted-2,2'-bipyridines, R = H, Me, and OMe) with tmtacn ligated in a facial fashion is found to be active as O-2-evolving catalysts. It is also found that the stronger electron-donating character of R(2)bpy gives rise to the higher O-2-evolving activity.
