In the title solvate, [Rh(2)(C(22)H(18)N(2)O(2))(C(8)H(12))(2)]·CH(2)Cl(2), each organometallic mol-ecule is composed of two Rh(I) cations, the tetra-dentate dianion α,α'-bis-(salicylaldiminato)-m-xylene and two 1,5-cyclo-octa-diene (COD) ligands. Each Rh(I) atom is coordinated by one O atom [Rh-O = 2.044 (2) and 2.026 (2) Å], one N atom [Rh-N = 2.083 (2) and 2.090 (2) Å], and one COD ligand vi...

The reactions of Me(2)NH·BH(3) with cationic Rh(III) and Ir(III) complexes have been shown to generate the 18-electron aminoborane adduct [Ir(IMes)(2)(H)(2){κ(2)-H(2)BNMe(2))](+) and the remarkable 14-electron aminoboryl complex [Rh(IMes)(2)(H)-{B(H)NMe(2))](+). Neutron diffraction studies have been used for the first time to define H-atom locations in metal complexes of this type formed under ...

The title compound, [Rh(C(5)H(7)O(2))(C(30)H(21)P)(CO)]·0.5C(3)H(6)O, has two different complex molecules in the asymmetric unit, with the Rh(I) atoms in slightly distorted square-planar coordination environments. The molecules are packed as two monomeric mol-ecules with one acetone solvent mol-ecule sitting at the centre.

Ammonium-based benzyl-NX3 (X = methyl, ethyl) trifluoromethanesulfonate (TFA) ionic liquids (ILs) are low cost, nontoxic, thermally stable ion-conducting electrolytes in fuel cells and batteries. In the present study, we have characterized the structure and dynamics of these ILs using molecular dynamics (MD) simulations and ionic conductivity using electro-chemical impedance spectroscopy (EIS) ...

A combined structural/EPR/computational chemistry investigation is reported on the two paramagnetic hydrido-cluster salts [Rh(6)(PCy(3))(6)H(12)][BAr(F)(4)] and [Rh(6)(PCy(3))(6)H(14)][BAr(F)(4)], the latter being formed by reversible addition of H(2) to the former, [BAr(F)(4)](-) = [B{C(6)H(3)(CF(3))(2)}(4)](-). The solid-state structure of [Rh(6)(PCy(3))(6)H(14)][BAr(F)(4)] shows an expanded ...

In two experiments with ovariectomized ewes, the plasma levels of LH and FSH were measured following passive immunization against LH-RH. The pulsatile secretion of LH was inhibited and the levels of the hormone fell quickly and were undetectable within 24 h. The levels of FSH fell more slowly and were always detectable. In the second of the experiments, pulses of LH of normal amplitude were re-...

This study was carried out with a recently developed model of focal cerebral ischemia in the rat based on the photochemical induction of thrombotic stroke using the dye Rose Bengal. We examined the change in the volume of the lesion and brain water content, in separate groups of rats, at different times (1, 4, 24, 72, and 168 h) after the induction of the ischemic lesion. The volume of ischemic...

Rh-based catalysts to be used for the synthesis of C -oxygenates from syngas were characterized with EPR, TPR, IR and 2 XPS methods. The chemical state of the Mn component was extensively studied with EPR after in situ reduction and treatment with various probe molecules. The results indicated that on the MnrSiO catalyst, Mn can exist as isolated Mn 2 ions on the surface of SiO through the form...

The chemistry of N-substituted amine-boranes and their reactivity towards transition metal centres is well established but the chemistry of B-substituted amine-boranes is not. Here we present the coordination chemistry of H2PhB·NMe3 towards a range of Rh(i) fragments with different P-Rh-P ligand bite angles, {Rh(P(i)Pr3)2}(+), {Rh(P(i)Bu3)2}(+), {Rh((i)Pr2P(CH2)3P(i)Pr2)}(+), {Rh(Ph2P(CH2)nPPh2...
