The mol-ecular structure of the title complex, [Ru2(C8H9OS)2Cl2(C10H14)2]·2CHCl3 or (p-MeC6H4Pr (i) )2Ru2(SCH2-p-C6H5-OCH3)2Cl2·2CHCl3, shows inversion symmetry. The two symmetry-related Ru(II) atoms are bridged by two 4-meth-oxy-α-toluene-thiol-ato [(4-meth-oxy-phen-yl)methane-thiol-ato] units. One chlorido ligand and the p-cymene ligand complete the typical piano-stool coordination environmen...

The hemerythrin-type dinuclear title complex, [Ru2(CH3COO)2O(C10H8N2)2(C5H5N)2](PF6)2, consists of two Ru(III) ions with a six-coordinate octa-hedral geometry, bridged by an oxide and two acetate ligands, with a bidentate 2,2'-bipyridine ligand and a pyridine ligand bonding at terminal positions. The Ru-Ru distance and Ru-O-Ru angle are 3.2838 (3) Å and 121.79 (7)°, respectively, and the averag...

Let X ⊂ P be a nondegenerate projective variety and let νl : P r → P be the l-th Veronese embedding. In this paper we study the higher normality, defining equations and syzygies among them for the projective embedding νl(X) ⊂ P N . We obtain that for a very ample line bundle L ∈ PicX such that X ⊂ PH(X,L) is m-regular in the sense of Castelnuovo-Mumford, (X,L) satisfies property Nl for all l ≥ ...

The ground- and excited-state acid-base properties of [Ru2(bpy)4(H2bipt)]Cl4 1 {bpy = 2,2'-bipyridine, H2bipt = 2,5-bis[1,10]phenanthrolin[4,5-f]-imidazol-2-yl)thiophene} are investigated by emission and UV-visible absorption spectrophotometric pH titrations. The DNA binding properties of 1 are studied by means of DNA viscosity and optical spectroscopic techniques of UV-visible absorption and e...

Hexaalkylguanidinium-based room-temperature ionic liquids were investigated as solvents for the cyclopropanation of styrene with diazoacetates catalyzed by Rh2(OAc)4 or [Ru2(μ-OAc)2(CO)4]n. While the yields of the formed cyclopropanes are much lower compared to the reactions performed in dichloromethane, the diastereomeric ratio is not significantly affected by the change of the reaction medium...

Density functional theory (DFT) has been used to determine the geometric and electronic structure of series [cis-{(?5-C5H3)2(CMe2)2}-Ru2(CO)4(?-H)n]n+ (n = 0, 1, 2) their di-tert-butyl-bipyridine (bipy) analogs ((CO)2 bipy). The results have analyzed by using natural bond orbitals (NBO) quantum atoms in molecules (QTAIM). This provide a thorough description changes bonding that occur as Ru-Ru n...

Ruthenium complexes have been considered as promising substitutes for cisplatin in cancer chemotherapy. However, novel ruthenium-based therapies are faced with some limitations, such as unimpressive cytotoxicity toward solid tumors. Herein, we designed and synthesized phenyl-substituted terpyridyl ruthenium(ii) complexes ([Ru(tpy)(bpy)Cl](+) (Ru1), [Ru(phtpy)(bpy)Cl](+) (Ru2) and [Ru(biphtpy)(b...
