General procedure: 2,2′-bipyridine (0.025 g, 0.16 mmol) was dissolved in DCM:MeOH 2:1 (6 mL) and [Ir(pyba)2(Cl)]2 (0.100 g, 0.08 mmol) was added. The mixture was heated at reflux under nitrogen atmosphere,in the dark. After 6 h, the yellow solution was cooled to room temperature. The crude solid was purified by column on silicaeluted with MeCN:H2O:KNO3 7:1:0.5. The yellow fractionwas driedunder vacuum, redissolved in acetonitrile and filtered. The solutionwas dried again and the solidwas dissolved in a minimal amount ofmethanol and NH4PF6 (130 mg, 0.9 mmol) was added allowed tostir overnight. The solution was left in the fridge for two hours,recrystallised with ether and then filtered on sintered glass. Ayellow powder was collected by filtration. (42 mg, yield 30%), 18511-72-3

The structural formula of the substituted bipyridine trivalent iron complex 4 described in this embodiment is as follows:Under an argon atmosphere, add anhydrous FeCl3 (64.9 mg, 0.4 mmol) to a 50 mL Schlenk bottle, and dissolve it in 6 mL of absolute ethanol at 60 C;A solution of 4,4′-dinitro-2,2′-bipyridine (98.5 mg, 0.4 mmol) in ethanol (4 mL) was added dropwise to the system. The reaction was carried out at 60 C for 1 hour.A brown complex was precipitated from the system, filtered, washed twice with cold ethanol, concentrated to remove the solvent, and dried under vacuum for 12 h to obtain a tan solid product 4, yield 67%.
