The preparation of a series of cis-[RuII(L–L)2(CO)L]n+ complexes [L–L-2,2′-bipyridyl (bipy), n= 1, L = H, Cl, or NCS; n= 2, L = H2O, MeCN, CO, pyridine (py), 4-vinylpyridine (vpy), or 4-methylpyridine (Mepy); L–L = 4,4′-dimethyl-2,2′-bipyridyl (Me2bipy), n= 1, L = H or Cl; n= 2, L = H2O or CO] is reported. The CO stretching frequency, the energy of the d–π* metal to ligand charge-transfer absorption

the trans(Cl,L)-[RuCl2(bpy)(CO)L] (L = NCNMe2, NCNEt2 or NCEt) isomer as the main products. The oxidation potential of the complexes decreases with the increase of the HOMO energy and of net electron-donor character of the ligands, the dialkylcyanamides (whose electrochemical Lever EL ligand parameter has been estimated) behaving as stronger net electron donors than propiononitrile or CO. The electronic

)2] (P3) and fac-[RuCl2(CO)3(dmso-O)] (P4) – which can be considered as “activated forms” of P2 and P1, respectively – towards the coordination of bpy. Compounds P3 and P4 allowed us to gain new mechanistic insight and a deeper level of understanding. In particular, we found that coordination of bpy to P4 (or P1) generates first the tricarbonyl cation fac-[Ru(bpy)Cl(CO)3]+. This key intermediate undergoes
