A process for making diphosphine-ruthenium-diamine complexes by reacting a phosphine compound with an arene ruthenium compound in a first solvent to produce an intermediate mixture comprising a diphosphine-ruthenium compound, the first solvent consisting essentially of a mixture of an aprotic solvent and a protic solvent; then removing the first solvent from the intermediate mixture to produce an intermediate solid comprising the diphospMne-ruthenium compound; and then contacting the intermediate solid comprising the diphosphine-ruthenium compound with a diamine and a second solvent to produce the diphosphine-ruthenium-diamine complex, the second solvent consisting essentially of an aprotic solvent selected from the group consisting of ethers and hydrocarbon solvents.

Reactions of <<(eta6-arene)RuCl(mu-Cl)>2> have been carried out with 4-cyanopyridine (4-CNpy), o-aminophenol (oap), o-phenylenediamine (opda), p-phenylenediamine (ppda) and 2,6-dimethyl-5-oxo-3-thioxo-2,3,4,5-tetrahydro-1,2,4-triazine (taz).The isolated complexes are of the types <(eta6-C6H6)RuCl2L> , <(eta6-C6H6)RuClL2>Cl or taz (VIa)> or <<(eta6-C6H6)Cl2Ru>2(mu-ppda)> (VIIIa).Complexes IVa and VIa undergo anion exchange with KPF6 to give the corresponding hexafluorophosphates (Va and VIIa).The p-cymene analogues (Ib-VIIIb) have been obtained.Conductance measurements, thermogravimetry and spectroscopic (IR and 1H and 13C NMR) methods have been used to study the new compounds.The structure of VIIb was determined by X-ray diffraction methods.The ruthenium atom of the cation of VIIb is coordinated by the 4-amino (Ru-N=2.140(2) Angstroem) and 3-thioxo (Ru-S=2.354(1) Angstroem) groups of the triazine and a chloride ligand (Ru-Cl=2.394(1) Angstroem).The eta6-p-cymene ring completes the hexacoordination.

Ru(II) eta6-arene complexes containing p-cymene (p-cym), tetrahydronaphthalene (thn), benzene (bz), or biphenyl (bip), as the arene, phenylazopyridine derivatives (C5H4NN:NC6H 5R; R = H (azpy), OH (azpy-OH), NMe2 (azpy-NMe 2)) or a phenylazopyrazole derivative (NHC3H 2NN:NC6H5NMe2 (azpyz-NMe 2)) as N,N-chelating ligands and chloride as a ligand have been synthesized (1-16). The complexes are all intensely colored due to metal-to-ligand charge-transfer Ru 4d6-pi* and intraligand pi ? piz.ast; transitions (epsilon = 5000-63 700 M-3 cm -1) occurring in the visible region. In the crystal structures of [(eta6-p-cym)Ru(azpy)Cl]PF6 (1), [(eta6-p- cym)Ru(azpy-NMe2)Cl]PF6 (5), and [(eta6-bip) Ru(azpy)Cl]PF6 (4), the relatively long Ru-N(azo) and Ru-(arene-centroid) distances suggest that phenylazopyridine and arene ligands can act as competitive pi-acceptors toward Ru(II) 4d6 electrons. The pKa* values of the pyridine nitrogens of the ligands are low (azpy 2.47, azpy-OH 3.06 and azpy-NMe2 4.60), suggesting that they are weak pi-donors. This, together with their pi-acceptor behavior, serves to increase the positive charge on ruthenium, and together with the pi-acidic eta6-arene, partially accounts for the slow decomposition of the complexes via hydrolysis and/or arene loss (t1/2 = 9-21 h for azopyridine complexes, 310 K). The pKa* of the coordinated water in [(eta6-p-cym)Ru(azpyz-NMe2)OH 2]2+ (13A) is 4.60, consistent with the increased acidity of the ruthenium center upon coordination to the azo ligand. None of the azpy complexes were cytotoxic toward A2780 human ovarian or A549 human lung cancer cells, but several of the azpy-NMe2, azpy-OH, and azpyz-NMe 2 complexes were active (IC50 values 18-88 muM).

Visible light driven water splitting in a dye-sensitized photoelectrochemical cell (DSPEC) based on a phosphonic acid-derivatized donor-pi-acceptor (D-pi-A) organic dye (P-A-pi-D) is described with the dye anchored to an FTO|SnO2/TiO2 core/shell photoanode in a pH 7 phosphate buffer solution. Transient absorption measurements on FTO|TiO2|-[P-A-pi-D] compared to core/shell, FTO|SnO2/TiO2(3 nm)|-[P-A-pi-D], reveal that excitation of the dye is rapid and efficient with a decrease in back electron rate by a factor of ?10 on the core/shell. Upon visible, 1 sun excitation (100 mW cm-2) of FTO|SnO2/TiO2(3 nm)|-[P-A-pi-D] in a phosphate buffer at pH 7 with 20 mM added hydroquinone (H2Q), photocurrents of ?2.5 mA cm-2 are observed which are sustained over >15 min photolysis periods with a current enhancement of ?30-fold compared to FTO|TiO2|-[P-A-pi-D] due to the core/shell effect. On surfaces co-loaded with both -[P-A-pi-D] and the known water oxidation catalyst, Ru(bda)(pyP)2 (pyP = pyridin-4-methyl phosphonic acid), maximum photocurrent levels of 1.4 mA cm-2 were observed which decreased over an 10 min interval to 0.1 mA cm-2. O2 was measured by use of a two-electrode, collector-generator sandwich cell and was produced in low faradaic efficiencies with the majority of the oxidative photocurrent due to oxidative decomposition of the dye.

The selective dehydrogenation of aqueous solutions of HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence of different monoaryl-biaryl or alkyl-biaryl phosphines and aryl diphosphines bearing sulfonated groups. All catalytic systems were used in water without any additives and proved to be active at 90 C, giving high conversions and good TOF values. As an alternative Ru(II) metal precursor, the known dimer [Ru(eta6-C6H6)Cl2]2 was also tested as in situ catalyst with selected phosphines as well as an isolated Ru(II)-catalyst with one of them. By using high-pressure NMR (HPNMR) techniques, indications on the nature of the active species involved in the catalytic cycles were obtained.
