The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, Computed Properties of C20H16Cl2N4Ru

A new polyazamacrocycle (L) containing two 2,2?-bipyridino (bpy) units, where the heteroaromatic nitrogen atoms point outwards from the macrocyclic cavity, was synthesized and characterized by elemental analysis, ESI-MS, 1H and 13C NMR, FTIR and TGA. Five protonation constants involving aliphatic nitrogens with log K in the range 9.39-3.07 were determined by potentiometry and NMR and a sixth protonation (log K = 2.2) involving a bipyridine moiety could be detected by UV-Vis and NMR titrations. The interaction of L with the cyanometallate anions [Pt(CN)4] 2- and [Co(CN)6]3- was studied by potentiometry yielding respectively log K values in the ranges 4.0-6.4 and 5.2-10.5, covering protonation degrees from 1 to 5. Studies on L with [Ru(CN)6] 4- led to early precipitation preventing potentiometry, but crystals of [H4L][Ru(CN)6]·10H2O and also of [H2L](ClO4)2·4H2O suitable for X-ray diffraction could be obtained and the crystalline structures are described. The interaction of L with Zn2+ was investigated by potentiometry and UV-Vis showing the formation of mono- and dinuclear complexes involving the bipyridines. The macrocycle was used as a bridging ligand for the successful synthesis of a new dinuclear [(Ru(bpy)2) 2(L)](PF6)4·4HPF6 complex that was fully characterized. The protonation (log K in the range 9.9-1.6) and coordination features of this compound towards Cu2+ and Zn 2+ were explored by UV-Vis absorption and emission spectroscopies.
