A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

Unusual photophysical properties of a ruthenium(II) complex related to [Ru(bpy)2(dppz)]2+
A new ruthenium polypyridyl complex, [Ru(bpy)2(dpqp)] 2+ (bpy = 2,2?-bipyridne; dpqp = pyrazino[2?,3?:5, 6]pyrazino[2,3-f][1,10]phenanthroline), shows strong luminescence in water at room temperature, a behavior that is strikingly different from that of the nonemissive “DNA light-switch” prototype [Ru(bpy)2(dppz)] 2+ (dppz = dipyrido[3,2-a:2?-3?-c]phenazine) under similar conditions. Variation of the absorption and emission spectra of [Ru(bpy)2(dpqp)]2+ as a function of the pH is consistent with the occurrence of two ground-state protonation steps associated with the dpqp ligand and an apparent pKa* of 2.1. Electrochemistry and theoretical calculations indicate that the lowest unoccupied molecular orbital (LUMO) of [Ru(bpy)2(dpqp)]2+ is localized on the distal portion of the dpqp ligand and lies at a lower energy than the dppz-based LUMO of [Ru(bpy)2(dppz)]2+. The combination of its strong DNA binding affinity and relatively long-lived triplet metal-to-ligand charge-transfer excited state in an aqueous solution results in more efficient DNA photocleavage by [Ru(bpy)2(dpqp)]2+ than [Ru(bpy) 2(dppz)]2+.
