Selective formation of ruthenium(IV) complexes with a monooxygen ligand: trans-[RuX(O)(py)4]+ (X = Cl, ONO)

Abstract: rrani-[RuCl(N02)(py)4] is oxidized chemically to give tmns-[RuCl(0)(py)4]+, while tmns-[Ru(N02)(H20)(py)4]+ yields the analogous ZraHi-[Ru(0N0)(0)(py)4]+ with retention of the nitro nitrogen. The origins of the oxygen ligand in each complex clearly differ. Electrochemical oxidation was also utilized to investigate the following chemical reaction processes: trans-[RuCl(N02)(py)4] generates, at 25 °C, three species, Zranr-[RuCl (NO) (py)4]2+, írans-[RuCl(OH)(py)4]+, and iraní-[RuCl-(0)(py)4]+, while 1.25 mol of … Show more

“…photodynamic therapy. 6,7 Linkage isomers of various ligands Z have been generated in [ML y L t Z] n complexes by direct chemical reactions, 8 by variation of temperature and through redox-reactions in solutions, [9][10][11][12] through electrochemical oxidation, [13][14][15][16] by pH, 17 and especially through light-irradiation. 3,[18][19][20] Here M is the central atom, usually a transition metal, L y are equatorial ligands with coordination number y, and L t is the ligand trans to the photoswitchable ligand Z (e.g.…”

“…RuCl 3 · 3H 2 O, bathophenanthrolinedisulfonic acid (dpsphen), 1,10‐phenanthroline, CTAB, SDS and Triton X‐100 obtained from Aldrich, India and Merck, India were used as supplied. The ruthenium(II) complexes, [Ru(phen) 3 ] 2+ ( I ), [Ru(phen) 2 (dpsphen)] ( II ), [Ru(phen)(dpsphen) 2 ] 2‐ ( III ) and [Ru(dpsphen) 3 ] 4‐ ( IV ) were prepared following a published procedure and the purity was confirmed by comparing the spectral data with the literature (see Supporting Information).…”

“…From the literature, we understand that the tris‐chelated complexes [Ru(dpphen) 3 ] 2+ and [Ru(dpsphen) 3 ] 4– have extensive application as sensors when incorporated into rigid media . Although some reports are available on the photophysics of these complexes in the presence of surfactants, a systematic study on changing the hydrophobic and electrostatic interaction of Ru(II) complexes using the ligand dpsphen has not been attempted previously.…”
