In the cation of the title salt, [Ag(C13H11N3)2]NO3, the Ag(I) atom lies on a crystallographic inversion center and is coordinated by four N atoms from two bidentate 2-(1H-benzimidazol-2-yl)aniline ligands in a distorted square-planar geometry. The Ag-N(aniline) bond [2.729 (2) Å] is significantly longer than the Ag-N(imidazole) bond [2.165 (1) Å]. In the ligand, the aniline ring is twisted by ...
A spongy change in the spinal cord white matter was observed in four-week-old rats treated with aniline. Although this change was found to be a result of the myelin sheath splitting at the ultrastructural level, the mechanism is unknown. This study was conducted to identify the mechanism of the spongy change in aniline-treated rats. The spongy change in the spinal cord white matter was first de...
Exposure of rats to aniline at daily doses of 50 mg/kg of body weight over a month stimulated the microsomal metabolism as manifested by (1) acceleration of p-hydroxylation of anilin and N-demethylation of aminopyrine in 9-000 times g postmitochondrial supernatant of the liver, (2) shortening the sleeping time after hexobarbital, and (3) reduction of the antipyretic effect of phenacetin. In the...
The asymmetric unit of the title compound, C(9)H(11)NO·C(6)H(5)N(3)O(4), contains two independent mol-ecules each of 4-(dimethyl-amino)-benzaldehyde and 2,4-dinitro-aniline. In the crystal, the components are linked by inter-molecular N-H⋯O hydrogen bonds to form one-dimensional chains along [10[Formula: see text]]. Intra-molecular N-H⋯O hydrogen bonds are also present.
The title compound, C7H10N2, was synthesized from 2-methyl-6-nitro-aniline by a reduction reaction. In the crystal, molecules are linked via N-H⋯N hydrogen bonds, forming two-dimensional networks lying parallel to (100). These networks are stabilized by C-H⋯π and N-H⋯π inter-actions.
The title compound, C(13)H(12)BrNO(4), was obtained from an optically active aniline derivative. The structure was characterized by (1)H NMR, (13)C NMR, MS and X-ray diffraction techniques. 86% of the atoms of the two independent mol-ecules in the asymmetric unit show non-crystallographic inversion symmetry.
The investigation of chemical co-polymerization aniline and ortho nitroanilinein acidic medium was done. Ammonium persulphate (APS) acted as the oxidizing agent. Synthesis PANI its copolymer done followed by characterization using FTIR analysis to assess bonding pattern. Detection copolymer, crystallinity orientation achieved XRD technique. To determine heat resistance TGA employed. One promine...
The Front Cover illustrates the photocatalytic reduction of CO2 to CO by an aniline-substituted Re-bipyridine-type photocatalyst in presence a strong electron donor (1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]-imidazole=BIH) N,N-dimethylacetamide. This catalyst absorbs visible light intensely compared related catalysts, and aniline moiety has beneficial effect on activity. More information ca...
