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.

Orientation tuning of a polypyridyl Ru(II) complex immobilized on a clay surface toward chiral discrimination
The present work reports an attempt to elucidate a stereoselective energy-transfer system by immobilizing a chiral metal complex on a clay surface. The metal complex used was [Ru(bpy)2Li]2+ with L1 = bpy (2,2a??-bipyridine), L2 = 4,4a??-diundecyl-2,2a??-bipyridine, and L3 = 5,5a??-diundecyl-2,2a??-bipyridine. The adsorption structure of [Ru(bpy)2Li]2+ was studied by means of electric dichroism measurements on an aqueous dispersion of a colloidal clay. It was found that the molecular orientation of the adsorbed Ru(II) complex was affected remarkably by the positions of the alkyl chains on the bpy ligand; that is, the angle of the 3-fold or pseudo-3-fold symmetry axis of the Ru(II) complex with respect to the surface normal was obtained to be 24A, 30A, and 52A for i = 1, 2, and 3, respectively. The efficiency of the energy-transfer was determined by photoluminescence quenching measurements between the adsorbed Ru(II) complex and [Ru(acac)3] (acac = acetylacetonate) in solution. As a result, stereoselectivity appeared most for the case of [Ru(bpy) 2L3]2+ in which its two helically twisted bpy ligands were projected in an outward direction. A 2005 American Chemical Society.
