A family of ruthenium(Ⅱ) polypyridyl complexes, namely[Ru(bpy)₂(DMBbimH_x)]^y+ (bpy=2, 2'-bipyridine, DMBbimH₂=7, 7'-dimethyl-2, 2'-bibenzimidazole, 1-A:x=2, y=2; 1-B:x=1, y=1; 1-C:x=0, y=0), were synthesized and determined by ¹H NMR, UV-Vis absorption and electrochemical measurements. With the deprotonation of N-H in DMBbimH_x ligands, the spectroscopic and electrochemical properties of complexes showed evident differences. Interestingly, the electrochemical properties of mono-deprotonated 1-B behaved very differently in dichloromethane and acetonitrile, which is due to different polarities of the solvents. In dichloromethane, mononuclear complex 1-B underwent a two-step oxidation. This is because[Ru(bpy)₂(DMBbimH)]⁺ cations are bonded by hydrogen bonds to form dimers in weakly polar solvent, and proton-coupled electron transfer (PCET) exists between the[Ru(bpy)₂ (DMBbimH)]⁺ cations. Single crystals of[Ru(bpy)₂(DMBbimH)]PF₆·2CH₂Cl₂ (2) were obtained from the solution of complex 1-B in dichloromethane. Crystal structure analysis shows that[Ru(bpy)₂(DMBbimH)]⁺ cations are bonded by hydrogen bonds to form dimers, which is consistent with the result of the electrochemical measurements. However, hydrogen-bonded dimers couldn't exist stably in the more polar acetonitrile, therefore only one peak existing in the CV curve.
