The title compound, C(13)H(9)Cl(2)NO, was crystallized from a methanol solution of 5-chloro-salicylaldehyde and o-chloro-aniline. The mol-ecule displays a trans configuration with respect to the imine C=N double bond. The N atom is involved in an intra-molecular O-H⋯N hydrogen bond. The two aromatic rings are essentially coplanar, the dihedral angle between them being 7.1 (1)°. A C-H⋯π inter-ac...

foot-and-mouth disease (fmd) is a major cause of endemic outbreaks in livestock in iran. in this study, clinical field samples of foot-and-mouth disease virus were collected from an outbreak in khorasan razavi province during april and august of 2010, and subjected to indirect sandwich elisa and rt-pcr. the viral serotype circulating during the period was confirmed to be type o. the virus was t...

The title compound, C(14)H(11)BrN(2)OS, was synthesized by the reaction of 1,2-benzothia-zol-3(2H)-one with formalin and 3-bromo-aniline in ethanol. The 1,2-benzothia-zolone ring system is approximately planar [maximum deviation = 0.0142 (s.u.?) Å] and forms a dihedral angle of 79.19 (5)° with the benzene ring. In the crystal, molecules are linked by N-H⋯O, C-H⋯O and C-H⋯Br interactions.

In the title compound, C(13)H(9)Cl(2)NO, the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-Cl atom in the aniline ring is positioned syn to the N-H bond. The two aromatic rings are almost coplanar, making a dihedral angle of 4.73 (5)°. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which link the mol-ecules into chains along the b axis.

The cation of the complex title salt, [Zn(C13H11N3)2(H2O)](NO3)2, lies about a twofold rotation axis, which passes through the Zn(II) atom and the O atom of the aqua ligand. The Zn(II) atom adopts a distorted trigonal-bipyramidal geometry defined by two N atoms in axial positions [angle = 166.24 (7)°], and two N and one O atom in the equatorial plane [range of angles: 115.17 (7)-122.42 (3)°]. T...

1. N-Hydroxyacetamidoaryl compounds (hydroxamic acids) are metabolites of arylamides, and an enzyme that transfers the acetyl group from these derivatives to arylamines has been found in rat tissues. The reaction products were identified by thin-layer chromatography and a spectrophotometric method, with 4-amino-azobenzene as acetyl acceptor, was used to measure enzyme activity. 2. The acetyltra...

The title compound, C(15)H(15)NO(3), was prepared by stirring benzoyl chloride with 3,5-dimeth-oxy-aniline in dioxane at ambient temperature. The dimeth-oxy-phen-yl-amide segment of the mol-ecule is almost planar, with a C-N-C=O torsion angle of -4.1 (4)°. The two benzene rings are inclined at an angle of 76.66 (13)°. In the crystal, inter-molecular N-H⋯O inter-actions generate centrosymmetric ...

The title compound, C(14)H(13)NO(2), was obtained by the condensation reaction of o-vanillin and aniline in ethanol. The mol-ecule adopts the phenol-imine tautomeric form and an E conformation with respect to the azomethine C=N bond. The dihedral angle between the aromatic rings is 30.57 (10)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds into zigzag chains para...

The Cu atom in the title compound, [Cu(NO(3))(2)(C(12)H(10)N(2))(CH(3)OH)], adopts a square-pyramidal geometry, being ligated by two N atoms of the bidentate N-(2-pyridylmethyl-ene)-aniline (ppma) ligand, two O atoms of NO(3) ligands and one O atom of a methanol molecule, which occupies the apical position. The phenyl ring on the ppma ligand is twisted out of the pyridine plane, forming a dihed...
