Six novel one-dimensional chloro-bridged ReIVCuII complexes of formula {[Cu(L)4][ReCl6]}n, where L = imidazole (Imi, 1), 1-methylimidazole (Meim, 2), 1-vinylimidazole (Vim, 3), 1-butylimidazole (Buim, 4), 1-vinyl-1,2,4-triazole (Vtri, 5) and N,N'-dimethylformamide (DMF, 6) are characterised structurally, magnetically and theoretically. The structures exhibit significant differences in Cu-Cl bon...

The title dinuclear copper(II) complex [Cu2(C18H16Br2N2O4S2)2] was prepared by direct synthesis of a dianionic Schiff base derived from 5-bromo-salicyl-aldehyde and cyste-amine. The discrete mol-ecules lie across inversion centers and crystallize with two di-methyl-formamide (DMF) mol-ecules of crystallization. The unique CuII ion is four-coordinated by two tetra-dentate Schiff base ligands in ...

The ditopic molecule 3-(1,3,5-trimethyl-4-1H-pyrazolyl)acetylacetone (HacacMePz) combines an acetylacetone group suitable for deprotonation and O,O? coordination to a Pearson hard cation with softer N-donor site. Both binding modes were employed individually: the pyrazolyl moiety was coordinated ZnII, HgII, AgI, trivalent iron tris-chelating complex [Fe(acacMePz)3] isolated. CuII derivative sho...

The interpeptidic CuII exchange rate constants were measured for two Cu amyloid-? complexes, Cu(A?1–16) and Cu(A?1–28), to fluorescent peptides GHW DAHW using a quantitative tryptophan fluorescence quenching methodology. second-order determined at three pH values (6.8, 7.4, 8.7) important the Cu(A?) coordination components Cu(A?)I Cu(A?)II. constant is approximately 104 M–1 s–1 but varies in ma...

Physicochemical and electrochemical properties of N,N,N-dimethylbutylammonium methanesulfonate, [DMBA][MS], ionic liquid (IL) have been determined, the potential application for recovery lead from lead-acid batteries is discussed. To optimise transport IL, dependences were measured conductivity, density viscosity with varying amounts excess acid water as a diluent in electrolyte mixture. Molar ...

A fast gas flow through a negative glow plasma creates an afterglow region where supercooled electrons are separated from energetic beam electrons to produce a population inversion by collisional recombination. We report spatially-resolved electron temperature measurements of the afterglow plasma showing electron temperatures in the range of 750-1100 K under steady-state conditions. A 4 em long...
