trimeric units in the asymmetric unit of [2]ClO4 (CH---O) via the involvement of ClO4– anions. The detailed electrochemical studies revealed metal-based oxidation of [RuII(Ph-trpy)(Cl)(L)]+ (1+–3+) to [RuIII(Ph-trpy)(Cl)(L)]2+ (12+–32+); however, the electronic form of the first reduced state (1–3) could be better represented by its mixed RuII(Ph-trpy)(Cl)(L•–)/RuIII(Ph-trpy)(Cl)(L2–) state. Both native (1+–3+)
