the reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [h4l]. the ligand was reacted with metal ions[cr(iii), mn(ii), fe(ii), co(ii), ni(ii), cu(ii), zn(ii), cd(ii), and hg(ii...

The title copper(II) complex, {(C27H37N2)[Cu4(CH3COO)8Cl]·3CH2Cl2} n , is a one-dimensional coordination polymer. The asymmetric unit is composed of a copper(II) tetra-acetate paddle-wheel complex, a Cl(-) anion situated on a twofold rotation axis, half a 1,3-bis-(2,6-diisoprop-ylphenyl)imidazolium cation (the whole mol-ecule being generated by twofold rotation symmetry) and one and a half of a...

The imine podands tris[(2-nitrobenzylidene)aminoethyl]amine and tris[(2-nitrobenzylidene)aminopropyl]amine both stabilize copper(I), forming {tris[(2-nitrobenzylidene)aminoethyl]amine-kappa4N}copper(I) perchlorate acetonitrile disolvate, [Cu(C27H27N7O6)]ClO4.2CH3CN, (II), and {tris[(2-nitrobenzylidene)aminopropyl]amine-kappa4N}copper(I) perchlorate, [Cu(C30H33N7O6)]ClO4, (VI), respectively. The...

PURPOSE As previously reported, magnesium sulphate administered parenterally significantly increased an opioid antinociception in different kinds of pain. Since the typical form of magnesium salts are poorly and slowly absorbed from the gastrointestinal tract we examined whether their micronized form could increase opioids induced antinociception. METHODS In behavioural studies on rats morphi...

anions. In the case of chloride and chloride and nitrate baths, it may be observed that only 40-60% of deposited copper is oxidized in the reverse potential sweep; these low charge recoveries are due to an disproportionation stage: the newly deposited copper reacts with the Cu~II! present in the reaction layer to form Cu~I!. For baths containing only nitrates, the efficacy of charge recovery is...

Ligand K-edge X-ray absorption spectroscopy (XAS) has been developed as a technique for the investigation of l&and-metal bonding and has been applied to the study of electronic structure in inorganic model complexes and metalloprotein active sites. Bonding in Cl-Cu(I1) Complexes. Ligand K-edge XAS has been measured at the chloride K-edge for a series of complexes containing chloride ligands bou...
