Two copper complexes, 1 and 2, with tridentate N-donor ligands, L(1) and L(2) [L(1)= (1-methyl-1H-imidazol-2-ylmethyl)-(2-pyridin-2-yl-ethyl)amine, L(2) = (2-pyridin-2-yl-ethyl)-pyridin-2 yl-methylamine] respectively, have been synthesized and characterized. On exposure to nitric oxide, the copper(II) centers in complexes 1 and 2 were found to undergo reduction in various solvents. In acetonitr...

In the title compound, [CoCl(CH5N)(C3H10N2)2]Cl2·H2O, the Co(III) ion has an octa-hedral coordination environment and is surrounded by four N atoms of two propane-1,3-diamine ligands in the equatorial plane, with another N atom of the methylamine ligand and a Cl atom occupying the axial positions. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯Cl, and O-H⋯Cl inter-actions, gene...

Context . In the near future, high spatial and spectral infrared (IR) data of star-forming regions obtained by James Webb Space Telescope may reveal new solid-state features various species, including more intriguing classes chemical compounds. The identification complex organic molecules (COMs) in upcoming will only be possible when laboratory IR ice spectra these species under astronomically ...

A hybrid electromagnetic nanomaterial, which is a matrix based on conjugated polymer of poly-3-amine-7-methylamine-2-methylphenazine with dispersed magnetite nanoparticles immobilized multi-walled carbon nanotubes, has been synthesized. In situ magnetometry was used to study the kinetics hydrogen reduction Fe3O4 in structure ternary nanocomposite magnetic fields different intensities. An increa...

“Creatininase” activity was induced in the colon flora of rats by feeding creatinine. Sarcosine and methylamine were tentatively identified as the major products of the enzymic action. A third (unidentified) compound was observed. These compounds and methylguanidine were labeled in the urine of rats given ‘CH3-creatinine orally. The resuits suggest that creatinine should not be considered biolo...

Symmetric and non-symmetric 2-(N-H, N-methyl, N-ethylenyl and N-aryl)guanidinebenzothiazoles were synthesized from the reaction of ammonia, methylamine, pyrrolidine and aniline with dimethyl benzo[d]thiazol-2-yl-carbonodithioimidate as intermediate. The products were characterized by ¹H-, ¹³C-NMR spectroscopy and three of them by X-ray diffraction analysis. HN-phenyl protons formed intramolecul...
