Ru(bbp)Cl3 (259 mg, 0.5 m mol) was added to a dmf solution (80 ml) of 4-(4-pyridyl) terpyridine (pyterpy) (155 mg, 0.5 m mol). Most of the Ru(bbp)Cl3 remained in suspended condition. The reaction mixture was refluxed under stirring condition. With the progress of the reaction, color of the reaction mixture changed from deep brown to pink. The mixture was refluxed for 20 h and filtered. The volume of the solution was reduced to 5 ml and a 2 ml saturated aqueous solution of NH4PF6 was added to give a pink colored solid. The solid was filtered and throughly washed with water (3 * 5 ml). The pink colored solid was dried under vacuum. Yield: 419 mg, 41%.

General procedure: [Ru(1)(3)](PF6)2 was prepared according to the literature procedure.[16] Ru(1)Cl3 (0.10 g, 0.19 mmol) and ligand 3 (0.06 g,0.19 mmol) were suspended in ethane-1,2-diol (10 mL) and heated at reflux for 2 h. The red solution was cooled to room temperature and excess aqueous KPF6 was added. The resulting red precipitate was collected on Celite, dissolved in acetonitrile,and purified by column chromatography (SiO2, MeCN/H2O/saturated aqueous KNO3 14 : 1.2 : 0.5). The main red band was collected, excess aqueous KPF6 was added, and the solvent volume reduced to give a fine red precipitate, which was collected on Celite and washed with water (20 mL), ethanol (10 mL), and diethyl ether (20 ml). The residue was dissolved in MeCN and the solvent removed to give [Ru(1)(3)](PF6)2 as a red powder (0.07 g, 0.07 mmol, 36 %).

The ligand Ptpy (pyridine terpyridine) was synthesised according to known procedures which involve the Kronke pyridine synthesis. A warm methanolic solution of Ptpy (0.310 g, 1 mM) was added to a MeOH solution of CuCl2¡¤2H2O (0.171 g, 1 mM) and kept for stirring for 3 h. A green precipitate was obtained in quantitative yield. After filtration the green precipitate was dissolved in methanol: acetonitrile (1:1) solution and heated to boil and kept aside for crystallization. Needle shaped crystals suitable for X-ray diffraction was obtained. Yield 86%.

General procedure: Ru(1)Cl3 (0.10 g, 0.17 mmol) and ligand 3 (0.05 g, 0.17 mmol) was suspended in ethane-1,2-diol (8 cm3). The suspension heated at 150 C for 2 h. The deep red solution was poured into excess aqueous KPF6 (20 mL). A red precipitate formed and was collected on Celite, washed with H2O (5 mL), EtOH (2 mL), Et2O (5 mL), and dissolved in CH3CN. The product was purified by chromatography (SiO2, CH3CN:H2O:saturated aqueous KNO3 14:1.2:0.5). Addition of excess aqueous saturated KPF6 solution and removal of CH3CN under reduced pressure gave a red precipitate which was collected on Celite, washed with H2O (5 mL), EtOH (2 mL), Et2O (5 mL) and dissolved in CH3CN. Removal of solvent gave [Ru(1)(3)](PF6)2 as a red solid (74 mg, 68 mumol, 40%)., 112881-51-3
