Complexation of cis-bis(2,2'-bipyridyl)dichlororuthenium(II) dihydrate with carboxaldehyde and carboxylate bearing ligand (4-carboxybenzaldehyde; (LII)-I-1) and with bis-acetyl and pyridine containing ligand (2,6-diacetylpyridine; L-2) yeilds (Ru(bpy)(3)](PF6)(2) = (bpy = 2,2'-bipyridyl), as the major product in both reactions along with (Ru(bpy)(2)(L-1)PF6 (1) and [Ru(bpy)(2)(L-2)](PF6)(2) (2) as minor products. However, reaction of cis-bis(2,2'-bipyridyl)dichlororuthenium(II) dihydrate with ligand containing bis-triazolo and diimino donor sites [1,4-bis(1,2,4-triazolo-3-imino)benzene; (LII2)-I-3] provides [Ru(bpy)(2)Cl-2]PF6 (3) crystals characterized by its single cystal X-ray data along with some unidentified product. Similar to ruthenium bipyridyl, reaction of (2,2'-bipyridyl)dichlorozine(II) monohydrate with L-2 has also been carried out which yields [Zn(bpy)(3)](PF6)(2) as a cystalline product along with a polymeric product with the composition [ {Zn(bpy)(L-2)Cl-2}center dot DMSO]n.
