“…The trans,cis-[Ru(I)(Me)(CO) 2 (iPr-DAB)] complex has C s symmetry, and in agreement with this a simple pattern for the 1 H and 13 C resonances is observed. [40] The corresponding cis,cis complex has no symmetry anymore and two sets of proton and carbon signals are therefore expected for the coordinated iPr-DAB ligand. These sets are indeed observed (see Experimental Section).…”

X-ray structure of [(CO)sMn-Ru(Me) (CO)a(a(N),a(N') Received 4 July 1994; revised 6 September 1994 AbstractThe synthesis and spectroscopy of the complexes [(CO)sMn-Ru(Me)(CO)2(a-diimine)] (a-diimine=N,N'-diisopropyl-l,4-diaza-l,3-butadiene (iPr-DAB), pyridine-2-carbaldehyde-N-isopropylimine (iPr-PyCa)) are reported. The metal fragments are bonded to each other by an uncommon manganese-ruthenium bond. The single crystal X-ray structure has been determined. The purple crystals of [(CO)sMn-Ru(Me)(CO)2(iPr-PyCa)] are monoclinic, space group P21/n, Z=4, with unit cell dimensions a = 9.6297(7), b = 20.923(1), c = 10.166(1) ~ and fl = 92.190(8) °. The structure refinement converged to R = 0.035 for 3277 observed reflections. Both complexes show a strong, solvatochromic absorption band in the visible region, which is assigned to Ru (d,~)~a-diimine (~-*) transitions. In agreement with this assignment, the Raman spectra show resonance enhancement of Raman intensity for vs(CO) and vs(CN) of the Ru(Me)(CO)2(a-diimine) fragment.

The photophysical, photochemical and redox properties of the title complexes were investigated. Resonance Raman measurements revealed the lowest‐energy electronic transition to possess σ→π* 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 fragments depending on the experimental conditions. (Spectro)electrochemical investigations of the title species proved that the axial [RuCp(CO)2] groups exert a stabilising influence on the corresponding radical cations, while destabilising the corresponding radical anions, compared to the redox behaviour of other ruthenium complexes of this type.
