“…For complexes 3 and 4, the redox potentials varied slightly based on the electronic nature of the donors and shifted to the negative direction. [37] The photocatalytic activity of ruthenium complexes 1-5 towards the water splitting hydrogen production within a cycle is shown in Figure 9. All of them exhibited certain photocatalytic activity and the amounts of evolved hydrogen after 30 min were 17.67 μmol, 15.81 μmol, 26.68 μmol, 25.32 μmol and 15.07 μmol for complexes 1-5, respectively.…”

Treatment of cis-[Ru(acac) 2 (CH 3 CN) 2 ] (acac À = acetylacetonate) with 1.5 equiv. of corresponding bidentate nitrogen and sulfur ligands in ethanol gave a series of bis(acetylacetonato) ruthenium(II/III) complexes [(acac 4) and [(acac) 2 Ru(S 2 CNMe 2 )] (5), respectively.Complexes 1-5 were characterized by FT-IR, NMR and UV-Vis spectroscopies along with their electrochemical properties. The structures of complexes 1-5 have been unambiguously established by single crystal X-ray crystallography. The photocatalytic properties for hydrogen production by water splitting of complexes 1-5 under visible light (λ > 420 nm) were also investigated in the paper.

The dianion derived from (2Z,6Z)‐3,7‐diphenyl‐N2,N6‐di(pyridin‐2‐yl)pyrrolo[2,3‐f]indole‐2,6(1H,5H)‐diimine (H2BL), a modified BODIPY ligand precursor, is shown to be capable of bridging two metal complex fragments RuL2, L=2,4‐pentanedionato (acac−), 2,2’‐bipyridine (bpy) or 2‐phenylazopyridine (pap) in [Ru(acac)2Ru(μ‐BL)Ru(acac)2] (1/2), [Ru(bpy)2Ru(μ‐BL)Ru(bpy)2](ClO4)2 ([3](ClO4)2) and [Ru(pap)2Ru(μ‐BL)Ru(pap)2](ClO4)2 ([4](ClO4)2). The compounds, including a diastereoisomeric pair 1 (meso) and 2 (rac) were spectroscopically and structurally characterized. Reversible electron transfers as revealed by cyclic and differential pulse voltammetry allowed for an EPR and UV‐vis‐NIR spectroelectrochemical investigation of several neighboring charge states. Together with susceptibility measurements and TD‐DFT calculations the assignment of oxidation states reveals that 1, 2 are diruthenium(III) species which can be oxidized or reduced by one electron whereas 32+ and 42+ contain ruthenium(II) and get reduced or oxidized mainly at the dianionic bridge (32+) or are reduced at the ancillary ligands pap (42+).
