Abstract: | Complexes cis-Ru(bpy)2(bipy)(X)]
n
+ bpy = 2,2'-bipyridyl, bipy = 4,4'-bipyridyl, X = Br-, ONO-, CN- (n = 1); MeCN, PPh3 (n = 2), and NO+ (n = 3)] were synthesized. Irradiation of acetonitrile solutions of the complexes with X = Cl-, Br-, ONO-, NO2-, CN-, NH3, MeCN, and PPh3 by visible light results in photosubstitution of 4,4'-bipyridyl by a solvent molecule. The electronic absorption spectra of the complexes were assigned on the basis of quantum-chemical calculations. A correlation was revealed between photolysis quantum yields and charges transferred from ligands X upon their coordination. |
