The title Schiff base zinc(II) complex, [Zn(C(13)H(10)ClN(2)O)I(CH(3)OH)], was synthesized by the reaction of 5-chloro-salicyl-aldehyde, 2-amino-methyl-pyridine and zinc iodide in methanol. The Zn(II) atom is five-coordinated by one phenolate O atom, one imine and one pyridine N atom of the Schiff base ligand, one methanol O atom and one I atom, forming a distorted square-pyramidal geometry, wi...

In the title compound, C11H13N3O, the seven-membered ring adopts a conformation such that the three atoms not involved in the aromatic plane lie on the same side of that plane. One hydrazinic H atom forms an intra-molecular hydrogen bond to the O atom; the other forms a classical inter-molecular hydrogen bond N-H⋯O, which combines with a 'weak' Har⋯O inter-action to build up double layers of mo...

In the title compound, C(17)H(20)N(2)O(2)S, the tetra-hydro-pyridine ring adopts an envelope conformation with the N atom at the flap position; the phenyl ring makes a dihedral angle of 81.06 (10)° with the thio-phene ring. The amino group links with the carbonyl O atom via intra-molecular N-H⋯O hydrogen bonding, forming a six-membered ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds ...

In the mol-ecule of the title compound, C(12)H(20)N(4)O(2), the dihydro-piperidine ring assumes a half-chair conformation. In the crystal, cllassical N-H⋯O and N-H⋯N inter-molecular hydrogen bonds link mol-ecules into double chains along the a axis.

In the title solvated molecular salt, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·CH(4)O, the pyridine N atom of 2-amino-4-methyl-pyridine is protonated and one carboxyl group of pyridine-2,6-dicarb-oxy-lic acid is deprotonated. The dihedral angles between the -CO(2) and -COH groups and the pyridine ring are 0.65 (13) and 7.4°. The crystal packing is stabilized by inter-molecular N-H⋯O, O-H⋯O and weak C...

The title compound, C(26)H(27)NO(4)S, with a thiophene ring fused to a quinoline ring, was synthesized via the condensation of dihydro-thio-phen-3(2H)-one 1,1-dioxide, 5,5-dimethyl-3-(phenyl-amino)cyclo-hex-2-enone and 3-methoxy-benzaldehyde in refluxing ethanol. In the crystal structure, the thiophene dioxide ring and the pyridine ring adopt envelope conformations. The connection of the pyridi...

In the title compound, C(21)H(16)FN(3)OS, the thieno[2,3-b]pyridine system forms dihedral angles of 10.57 (12) and 83.87 (5)° with the fluoro-phenyl ring at the 6-position and the phenyl ring of the benzyl group, respectively. In the crystal, mol-ecules are linked by weak N-H⋯N anf N-H⋯O hydrogen bonds and π-π stacking inter-actions involving fluoro-phenyl rings of adjacent mol-ecules, with a c...

Abstract The Pt(II) acetylacetonate complex [(L)Pt(Acac)] based on aminophenyl-substituted 2-(2-thienyl)pyridine (L) was synthesized, its photophysical properties were studied and compared with these for a similar containing no amino group in the ligand. structure of confirmed by X-ray diffraction (CIF file CCDC no. 2144689), 1 H 13 C NMR spectroscopy, ESI mass spectrometry, elemental analysis.

The crystal structures of N'-amino-pyridine-2-carboximidamide (C6H8N4), 1, and N'-{[1-(pyridin-2-yl)ethyl-idene]amino}-pyridine-2-carboximidamide (C13H13N5), 2, are described. The non-H atoms in compound 1 are nearly planar (r.m.s. deviation from planarity = 0.0108 Å), while 2 is twisted about the central N-N bond by 17.8 (2)°. Both mol-ecules are linked by inter-molecular N-H⋯N hydrogen-bondin...
