摘要：
The photochemical properties of Ru(II) mono(bipyridine) complexes Ru(L)(CO)(2)Cl-2 [L = 2,2'-bipyridine (1, 2) or 4,4'-dimethyl-2,2'-bipyridine (3)] were studied in CH3CN and CH2Cl2. Photochemical ligand substitution reactions occurring in CH3CN were followed by infrared and H-1 NMR spectroscopies and cyclic voltammetry. The structures of the photolysis products Ru(bpy)(CO)(CH3CN)Cl-2 (4), mer-(CH3CN) Ru(bpy)(CH3CN)(3)Cl+ (6), and fac(CH3CN) Ru(dmbpy)(CH3CN)(3)Cl+ (8) were determined by single-crystal X-ray crystallography. Photosubstitution of the trans (1) and cis (2) Cl isomers of Ru(bpy)(CO)(2)Cl-2 (bpy = 2,2'-bipyridine) led to the same monosubstituted Ru(bpy)(CO)(CH3CN)Cl-2 complex (4). Probably some isomerization occurs from the traits Cl isomer. Irradiation in CH2Cl2 led mainly to the dichloro-bridged [Ru(bpy)(CO)Cl-2](2) (5) dimer starting from either the trans (1) or cis (2) isomer of Ru(bpy)(CO)(2)Cl-2.
