The treatment of [Ru^VI(N)(L)(MeOH)]PF₆ (1) (L = N,N′-bis(salicylidene)-o-cyclohexyldiamine dianion) with 2 equiv of RNC (R = (a) ^tBu, (b) Cy) in CH₂Cl₂ affords a mixture of blue cis-β-[Ru^III(NCNR)(L)(CNR)] (2) and green trans-[Ru^III(L)(CNR)₂]PF₆ (3) products. The reduction of 3 with a stoichiometric amount of Cp₂Co in CH₃CN gives red trans-[Ru^II(L)(CNR)₂] (4). Refluxing 4 with 3 equiv of RNC in methanol in the presence of 5 equiv of NH₄PF₆ affords a yellow complex, mer-[Ru^II(η³-HL)(CNR)₃](PF₆) (5), in which the ligand is in an η³-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.
