Temperature-Dependent Photophysical, Photochemical and Redox Properties of Novel Complexes (CO)2CpRu–Ru(Ln)–RuCp(CO)2 and (CO)2CpRu–Ru(Ln)–SnPh3 [Ln = (CO)2(N,N′-diisopropyl-1,4-diaza-1,3-butadiene)]

The photophysical, photochemical and redox properties of the title complexes were investigated. Resonance Raman measurements revealed the lowest-energy electronic transition to possess σπ* character. At low temperatures, long-lived near-IR emission was observed. Irradiation in solution results in homolytic splitting of a Ru–Ru bond as the primary step, followed by secondary reactions of the radical
