Abstract: Complexation of cis-bis(2,2'-bipyridyl)dichlororuthenium(II) dihydrate with carboxaldehyde and carboxylate bearing ligand (4-carboxybenzaldehyde; L¹H) and with bis-acetyl and pyridine containing ligand (2,6-diacetylpyridine; L²) yields [Ru(bpy)₃](PF₆)₂ (bpy = 2,2'-bipyridyl), as the major product in both reactions along with [Ru(bpy)₂(L¹)]PF₆ (1) and [Ru(bpy)₂(L²)](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; L³H₂] provides [Ru(bpy)₂Cl₂]PF₆ (3) crystals characterized by its single crystal X-ray data along with some unidentified product. Similar to ruthenium bipyridyl, reaction of (2,2'-bipyridyl)dichlorozinc(II) monohydrate with L² has also been carried out which yields [Zn(bpy)₃](PF₆)₂ as a crystalline product along with a polymeric product with the composition [{Zn(bpy)(L²)Cl₂}•DMSO] ո.
