The treatment of [Ru VI(N)(L)(MeOH)]PF 6 (1) (L=N,N′-bis(salicylidene)-o-cyclohexyldiamine dianion) with 2 equiv of RNC (R ) (a) tBu, (b) Cy) in CH 2Cl 2 affords a mixture of blue cis-β-[Ru III(NCNR)(L)(CNR)] (2) and green trans-[Ru III(L)(CNR) 2]PF 6 (3) products. The reduction of 3 with a stoichiometric amount of Cp 2Co in CH 3CN gives red trans-[RuII(L)(CNR) 2] (4). Refluxing 4 with 3 equiv of RNC in methanol in the presence of 5 equiv of NH 4PF 6 affords a yellow complex, mer-[RuII(η 3-HL)(CNR) 3](PF 6) (5), in which the ligand is in an η 3-coordination mode. These complexes are characterized by IR, UV-vis, ESI-MS, CV, magnetic measurements, and CHN elemental analysis. The structures of 2a, 3a, 4a, 4b, and 5a have been determined by X-ray crystallography.
