In the title compound, C(33)H(28)N(3)PS, the P atom has a distorted tetra-hedral PNC(3) environment, formed by the N atom and three aryl rings. No inter-molecular hydrogen-bonding inter-actions or π-π stacking inter-actions are present in the crystal structure.

The title compound, C(8)H(8)N(6)O, was obtained by the reaction of 3,5-diamino-1,2,4-triazole with ethyl 2-picolinate in a glass oven. The dihedral angles formed between the plane of the amide group and the pyridine and triazole rings are 11.8 (3) and 5.8 (3)°, respectively. In the crystal, an extensive system of classical N-H⋯N and N-H⋯O hydrogen bonds generate an infinite three-dimensional ne...

In the present study, a series of 2-(3'-substituted-2'-hydroxypropylamino)pyridines were synthesized and characterized by IR, 1H-NMR and elemental analysis. The compounds were investigated for anticonvulsant (150, 300 mg/kg) and cardiac activity. 2-(3'-Diethylamino-2'-hydroxypropylamino)pyridine 3 was found to exhibit the highest anticonvulsant activity. 2-(3'-Dimethylamino-2'-hydroxypropylamin...

The 2'-deoxy-beta-D-ribonucleosides of 1,3-deazapurine (benzimidazole (1)), 1-deazapurine (both 1H-imidazo[4,5-b]pyridine (2) and 3H-imidazo[4,5-b]pyridine (3)), and 6-benzoylamino-1-deazapurine (7-benzoylamino-3H-imidazo[4,5-b]pyridine (4)) have been prepared and structurally characterized by X-ray crystallography. Especially compounds 1-3 can serve as artificial nucleosides that may substitut...

The asymmetric unit of the title compound, C19H12ClN3O, contains two mol-ecules with similar conformations. The 14 non-H atoms comprising the 4H-chromeno[8,7-b]pyridine residue are essentially coplanar (r.m.s. deviations = 0.037 and 0.042 Å for the two mol-ecules) and the main difference between them is seen in the twist about the bond linking the main residue to the attached chloro-benzene rin...

The title compound, C(22)H(14)FN(3), was prepared by a one-pot condensation using malononitrile, an aromatic aldehyde, a methyl ketone and ammonium acetate as reacta-nts under microwave irradiation. The pyridine ring is twisted with respect to the benzene ring and the naphthalene ring system, making dihedral angles of 41.9 (1) and 45.2 (1)°, respectively. In the crystal, mol-ecules are connecte...

The title compound, [RuCl(C10H14)(C11H10N4)]Cl is an Ru(II) complex in which an η (6) -p-cymene ligand, two N atoms of 3-amino-2-(phenyl-azo)pyridine and one Cl ion form a piano-stool coordination environment around the metal ion. In the crystal structure, N-H⋯Cl hydrogen bonds play an important role in the formation of the supramolecular zigzag chain along the a-axis direction. Disorder is obs...
