The asymmetric unit of the title compound, [RuCl2(C6H6)(C18H27P)]·1.5C6H6, contains one mol-ecule of the Ru(II) complex and one and a half solvent molecules as one of these is located about a centre of inversion. The Ru(II) atom has a classical three-legged piano-stool environment being coordinated by an η(6)-benzene ligand [Ru-centroid = 1.6964 (6) Å], two chloride ligands with an average Ru-C...

The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(18)H(14)BrP)(CO)(9)]·0.3CHCl(3), contains one mol-ecule of the triangulo-triruthenium complex and one partially occupied disordered chloro-form solvent mol-ecule. The bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the arsine...

Density functional theory (DFT) calculations were carried out to study the nucleation and growth mechanism of Ru clusters on the TiO2(101) surface by using supported Run (n = 1−10, 20, 22) cluster models to understand the metal−support interaction and the resulting catalytic performance toward CO oxidation. The results show that the Run cluster prefers a 3D geometry when n ≥ 4 and that the Ru−T...

The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(20)H(19)O(2)P)(CO)(9)]·0.15CH(2)Cl(2), contains one mol-ecule of the triangulo-triruthenium complex and one partially occupied dichloro-methane solvent mol-ecule. The dichloro-methane solvent lies across a crystallographic inversion center leading to the mol-ecule being disordered over two positions of e...

The title compound, trans-[Ru(bpy)(2)(H(2)O)(2)](CF(3)SO(3))(2) (bpy = 2,2'-bipyridine, C(10)H(8)N(2)), crystallized from the decomposition of an aged aqueous solution of a dimeric complex of cis-Ru(bpy)(2) in 0.1 M triflic acid. The Ru(II) ion is located on a crystallographic inversion center and exhibits a distorted octa-hedral coordination with equivalent ligands trans to each other. The Ru-...

We employed RU 38486, a potent and selective antiglucocorticoid, to study a possible role for endogenous glucocorticoids in atrophy of the levator ani muscle secondary to castration of male rats. RU 38486 was shown to block [3H]triamcinolone acetonide binding to cytosol from levator ani muscle. Daily oral administration of RU 38486 to castrated rats partially prevented atrophy of the levator an...

It has appeared that the currently dominant identifications of the ha-BI-ru as a social class of one sort or another are inadequate. They fail to discover a common denominator for all the ha-BI-ru (and the ha-BI-ru alone) that will satisfy all the known documents. The investigation must turn to other possibilities. Was ethnic unity the peculiar stamp of the ha-BI-ru? Was their hallmark the prac...

introduction: previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. to clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. methods: 140 ...

The asymmetric unit of the title compound, [FeRuCl(C(5)H(5))(C(10)H(14))(C(37)H(31)P(2))]PF(6), contains two independent, geometrically similar Ru(II) complexes of a chiral ferrocenyldiphosphane with piano-stool coordination through the η(6)-bound p-cymene ligand, two chelating phospho-rus donor atoms, and an exo-oriented chloride ion. The mean bond lengths of the two Ru complexes are Ru-C = 2....

RU-486, or mifepristone, can work as a contraceptive, as an emergency contraceptive, or as an abortifacient. It has the potential to dramatically increase the privacy of procreative choice. For this to happen, RU-486 must fall under the protection of contraception law rather than the law of abortion. Contraception law constitutionally guarantees access to contraception, including emergency cont...
