Dichlorido(?-p-cymene)(4-fluoro-aniline-?N)ruthenium(II).

ABSTRACT: The title compound, [RuCl(2)(C(10)H(14))(C(6)H(6)FN)], a pseudo-octa-hedral d(6) complex, has the expected piano-stool geometry around the Ru(II) atom. The fluoro-aniline ring forms a dihedral angle of 19.3?(2)° with the p-cymene ring. In the crystal, two mol-ecules form an inversion dimer via a pair of N-H?Cl hydrogen bonds. Weak inter-molecular C-H?Cl inter-actions involving the p-cymene ring consolidate the crystal packing.

Dichlorido(?(6)-p-cymene)(eth-oxy-diphenyl-phosphane)ruthenium(II).

Project description:The title compound, [RuCl2(C10H14)(C14H15OP)], is an Ru(II) complex in which an ?(6)-p-cymene ligand, two chloride anions and the P atom of an ethoxydiphenylphosphane ligand form a piano-stool coordination environment about the central Ru(II) atom.

p-Cymene Complexes of Ruthenium(II) as Antitumor Agents.

Project description:In this work, the cytotoxic behavior of six ruthenium(II) complexes of stoichiometry [(η6-p-cymene)RuCl2L] (I-VI), L = 4-cyanopyridine (I), 2-aminophenol (II), 4-aminophenol (III), pyridazine (IV), and [(η6-p-cymene)RuClL2]PF6; L = cyanopyridine (V), L = 2-aminophenol(VI) towards three cell lines was studied. Two of them, HeLa and MCF-7, are human carcinogenic cells from cervical carcinoma and human breast cancer, respectively. A comparison with healthy cells was carried out with BGM cells which are monkey epithelial cells of renal origin. The behavior of complex II exhibits selectivity towards healthy cells, which is a promising feature for use in cancer treatment since it might reduce the side effects of most current therapies.

Dichlorido(dimethyl sulfoxide-?S)(?-mesitylene)ruthenium(II).

Project description:The title compound, [RuCl(2)(C(9)H(12))(C(2)H(6)OS)], features a planar [maximum deviation = 0.0075?(17)?Å] ?(6)-bound mesitylene ligand and a dimethyl sulfoxide ligand coordinated via the S atom. The overall complex geometry about the Ru(II) atom is best described as a piano-stool configuration.

(?-p-Cymene)bis-(trichlorido-stannyl)(triethoxy-phosphine-?P)ruthenium(II).

Project description:In the title complex, [RuSn(2)(C(10)H(14))Cl(6)(C(6)H(15)O(3)P)], the Ru-Sn bond lengths [2.5619?(3) and 2.5669?(3)?Å] are about 0.3?Å shorter than the sum of the covalent Ru and Sn radii (1.46 + 1.39 = 2.85?Å), in line with other structurally characterized arene ruthenium trichlorido-stannyl derivatives. The Ru(II) atom is surrounded by a para-cymene, a triethylphosphite and two trichloridostannyl ligands in a typical piano-stool coordination.

Organometallic <i>cis</i>-Dichlorido Ruthenium(II) Ammine Complexes.

Project description:Bifunctional neutral half-sandwich RuII complexes of the type [(?6-arene)Ru(NH3)Cl2] where arene is p-cym (1) or bip (2) were synthesised by the reaction of N,N-dimethylbenzylamine (dmba), NH4PF6 and the corresponding RuII arene dimer, and were fully characterised. X-ray crystallographic studies of [(?6-p-cym)Ru(NH3)Cl2]·{(dmba-H)(PF6)} (1a) and [(?6-bip)Ru(NH3)Cl2] (2) show extensive H-bond interactions in the solid state, mainly involving the NH3 and the Cl ligands, as well as weak aromatic stacking interactions. The half-lives for the sequential hydrolysis of 1 and 2 determined by UV/Vis spectroscopy at 310 K ranged from a few minutes for the first aquation to ca. 45 min for the second aquation; the diaqua adducts were the predominant species at equilibrium. Arene loss during the aquation of complex 2 was observed. Upon hydrolysis, both complexes readily formed mono- and di-9-ethylguanine (9-EtG) adducts in aqueous solution at 310 K. The reaction reached equilibrium after ca. 1.8 h in the case of complex 1 and was slower but more complete for complex 2 (before the onset of arene loss at ca. 2.7 h). Complexes 1 and 2 were not cytotoxic towards A2780 human ovarian cancer cells up to the maximum concentration tested (100 ?M).

Dichlorido(furfuryl-amine-?N)(?-hexa-methyl-benzene)-ruthenium(II).

Project description:The single-crystal X-ray structure analysis of [RuCl(2)(C(12)H(18))(C(5)H(7)NO)] reveals a distorted piano-stool geometry around the Ru(II) atom, with a hexa-methyl-benzene ligand, two chloride ligands and a furfuryl-amine ligand, the latter coordinating through the amine group. In the crystal, a dimeric structure is observed as a result of N-H?Cl inter-actions between two symmetry-related mol-ecules.

Dichlorido(?-toluene)[tris-(4-methoxy-phen-yl)phosphine]ruthenium(II).

Project description:In the title compound, [RuCl(2)(C(7)H(8))(C(21)H(21)O(3)P)], the Ru(II) atom possesses a pseudo-octa-hedral geometry and the metrical parameters around the metallic core compare well with those of similar three-legged-piano-stool complexes.

Bis(acrylonitrile-?N)dichlorido(?-cyclo-octa-1,5-diene)ruthenium(II).

Project description:In the title complex, [RuCl(2)(C(8)H(12))(C(3)H(3)N)(2)], the metal ion is coordinated to centers of each of the double bonds of the cyclo-octa-1,5-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors from two acrylonitrile mol-ecules that complete the coordination sphere for the neutral complex. The coordination about the Ru(II) atom can thus be considered octa-hedral with slight trigonal distortion. The three C atoms of one of the acrylonitrile ligands are disordered over two sets of sites in a 0.581?(13):0.419?(13) ratio.

?-Pyrazine-2,5-dicarboxyl-ato-bis-[chlorido(?-p-cymene)ruthenium(II)] tert-butanol disolvate.

Project description:A new tert-butanol solvate of [{((i)PrC(6)H(4)Me)RuCl}(2){?-2,5-pyz(COO)(2)}] (pyz = pyrazine) has been crystallized and structurally characterized. The solvate, [Ru(2)(C(10)H(14))(2)(C(6)H(2)N(2)O(4))Cl(2)]·2C(4)H(10)O, contains one half-mol-ecule of the ruthenium(II) complex and one mol-ecule of tert-butanol in the asymmetric unit. The complex mol-ecule lies on an inversion centre with the two chlorides trans. In contrast, the previously reported structure was solvent-free. Similar metric parameters are found between the butanol solvate and the solvent-free form and an inter-molecular O-H?O hydrogen bond exists between ?-pyrazine-2,5-dicarboxyl-ato-bis-[chlorido(?(6)-p-cymene)-ruthenium(II)] and the tert-butanol mol-ecule.

Dichlorido(?-cyclo-octa-1,5-diene)bis-(propane-nitrile-?N)ruthenium(II).

Project description:In the title complex, [RuCl(2)(C(8)H(12))(C(3)H(5)N)(2)], the metal ion is coordinated to both double bonds of the cyclo-octa-1,5-diene ligand, two chloride ions (in cis positions) and two N-atom donors from two propane-nitrile mol-ecules that complete the coordination sphere for the neutral complex. The coordination around the Ru(II) atom can thus be considered as octa-hedral with slight trigonal distortion.
