Monoand homobinuclear Ru (II) complexes were prepared by the reaction of [Ru (bipy) 2Cl2] H2O with 4-amino-3,5-dI (2-byridyl) -4H-1,2,4-triazole (adapt); ( 4-byridyl) -3,5-dI (2-byridyl) -4H-1,2,4-triazole (Pydpt), and 4-( 4-methylphenyl) -3,5-DI (2-byridyl) -4H-1,2,4-triazole (mpdpt). The products were characterized by elemental analysis, IR, electronic and 1H NMR spectral however molar conduc...

Delivery agents which can carry the {Ru(NO)}(6) chromophore ("caged NO") are desired for vasodilation and for photodynamic therapy of tumors. Toward these goals, complexes derived from [RuCl(3)(NO)(H(2)O)(2)]= (1) have been prepared using dipyridylamine (dpaH) as mono and bis adducts, [Ru(NO)Cl(3)(dpaH)] = (2) and [Ru(NO)Cl(dpaH)(2)]Cl(2) = (3). The dpaH ligands coordinate cis to the Ru(NO) axi...

The Ru(III)(edta)/H(2)O(2) system (edta(4-) = ethylenediaminetretaacetate) was found to degrade the azo-dye Orange II at remarkably high efficiency under ambient conditions. Catalytic degradation of the dye was studied by using rapid-scan spectrophotometry as a function of [H(2)O(2)], [Orange II] and pH. Spectral analyses and kinetic data point towards a catalytic pathway involving the rapid fo...

[Ru(terpy)(bpy)(L)]PF6 complexes, where terpy is 2,2 ́:6′,2′′– terpyridine, bpy is 2,2 ́ bipyridine and L is monoanions of 4 bromophenylcyanamide (4 Brpcyd), 4methoxyphenylcyanamide (4 MeOPcyd), 2, 4 dibromophenylcyanamide (2,4 Br2pcyd), 2,4dimethylphenylcyanamide (2,4 Me2pcyd), 2 methylphenylcyanamide (2 MePcyd), phenylcyanamide (Pcyd) and naphtylcyanamide (ncyd) have been prepared and character...

The synthesis and spectroscopic characterisation of novel mononuclear Ru(III)(edta)(hydroxamato) complexes of general formula [Ru(H2edta)(monoha)] (where monoha = 3- or 4-NH2, 2-, 3- or 4-C1 and 3-Me-phenylhydroxamato), as well as the first example of a Ru(III)-N-aryl aromatic hydroxamate, [Ru(H2edta)(N-Me-bha)].H2O (N-Me-bha = N-methylbenzohydroxamato) are reported. Three dinuclear Ru(III) com...

The reactions of the ruthenium hydride complexes [{Ru(COD)(H)(NH2NMe2)3}{BArF}] (BArF=B{C6H3(CF3)2}4), [{Cp*Ru}2(micro-H)4] and [{Cp*Ru}3(micro-H)3(micro3-H)2] with GaCp* and AlCp* are investigated. The reaction of [{Ru(COD)(H)(NH2NMe2)3}{BArF}] with GaCp* leads to substitution of the hydrazine ligands by GaCp* and the formation of [{Ru(COD)(H)(GaCp*)3}{BArF}] (), while the reactions of [{Cp*Ru...

In this work, we introduce a novel concept of a borane group vicinal to a metal boryl bond acting as a supporting hemilabile ligand in exohedrally metalated three-dimensional carborane clusters. The (POBOP)Ru(Cl)(PPh3) pincer complex (POBOP 1⁄4 1,7-OP(i-Pr)2-m-2-carboranyl) features extreme distortion of the two-center-two-electron Ru–B bond due to the presence of a strong three-centertwo-elect...

Octahedral, trigonal prismatic, and capped square pyramidal structures have been optimized for the Ru(6)C(CO)(n) clusters (15 ≤ n ≤ 20) using density functional theory. The experimentally known very stable Ru(6)C(CO)(17) is predicted to have an octahedral structure in accord with experiment as well as the Wade-Mingos rules. The stability of Ru(6)C(CO)(17) is indicated by its high carbonyl disso...

A Ru complex-incorporated Ti-based MOF (Ti-MOF-Ru(tpy)2) has been synthesised by using a bis(4'-(4-carboxyphenyl)-terpyridine)Ru(ii) complex (Ru(tpy)2) as an organic linker. Ti-MOF-Ru(tpy)2 promotes photocatalytic hydrogen production from water containing a sacrificial electron donor under visible-light irradiation up to 620 nm.
