Novel Triple-Decker dinuclear Sandwich Nd (III) -(bis-N,N'-p- bromo-salicylideneamine-1,2-diaminobenzene) Complex
In the search of new multifunctional molecular materials, the present paper introduces the work performed with the Salen-type Schiff base: bis-N,N'-p-bromo-salicylideneamine-1,2-diaminobenzene (H2bsph), to attain novel coordination complexes containing lanthanides centers (LnIII). So far, our studies have shown that the combination in acetone of the well-known H2bsph ligand, a base and NdIII (NO3)3·6H2O, results in a yellow solid which crystalline forms ... Read more

Carbon steel pipelines corrosion inhibition by some novel imines during acidizing treatment of oil wells: Electrochemical and quantum chemical studies
The corrosion protection of the equipments and vessels is one of chief concerns of the maintenance and design engineers. From this point of view, three novel imine compounds were prepared and their structures were characterized by X-ray, 13C-NMR, 1H-NMR, mass, UV-Vis, FT-IR, spectral data and elemental analyses. The corrosion inhibition of the investigated inhibitors towards carbon steel in 15% HCl ... Read more

Ethyl 2-[({[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]carbamoyl}methyl) sulfanyl]acetate monohydrate
The title compound, C13H16N4O3S2H2O, crystallizes in a ‘folded’ conformation with the ester group lying over the carbamoyl moiety, with one solvent water molecule. The molecular conformation is stabilized by an intramolecular C—H O hydrogen bond, and an N—H O hydrogen-bonding interaction involving the lattice water molecule. The packing involves N—H N, N—H O, O—H N and O—H O hydrogen bonds ... Read more
