Crystal structure of 7-{[bis(pyridin-2-ylmethyl)amino]methyl}-5-chloroquinolin-8-ol
In the title compound, C22H19ClN4O, the quinolinol moiety is almost planar [r.m.s. deviation = 0.012 Å]. There is an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy group and a pyridine N atom forming an S(9) ring motif. The dihedral angles between the planes of the quinolinol moiety and the pyridine rings are 44.15 (9) and 36.85 (9)°. In the crystal, mol-ecules are linked via C-H⋯O ...

In the crystal structure of the title compound, C(6)H(7)NO(2), the mol-ecules are are linked by inter-molecular O-H⋯N and O-H⋯O hydrogen bonds; π-π stacking is observed between parallel pyridine rings of adjacent mol-ecules [centroid-to-centroid distance = 3.7649 (12) Å].
متن کاملCrystal structure of naltrexone chloride solvates with ethanol, propan-2-ol, and 2-methylpropan-2-ol
Naltrexone [systematic name: 17-(cyclo-propyl-meth-yl)-3,14-di-hydroxy-4,5α-epoxymorphinan-6-one] is an opioid receptor competitive antagonist that has been widely used to prevent relapse in opioid- and alcohol-dependent subjects. Its chloride salt forms non-isomorphic solvates with ethanol (C20H24NO4+·Cl-·C2H5OH) (I), propan-2-ol (C20H24NO4+·Cl-·C3H7OH) (II), and 2-methyl-propan-2-ol (C20H24NO...
متن کاملCrystal structure of 2-hydroxyimino-2-(pyridin-2-yl)-N′-[1-(pyridin-2-yl)ethylidene]acetohydrazide
The mol-ecule of the title compound, C14H13N5O2, is approximately planar (r.m.s deviation for all non-H atoms = 0.093 Å), with the planes of the two pyridine rings inclined to one another by 5.51 (7)°. The oxime group is syn to the amide group, probably due to the formation of an intra-molecular N-H⋯N hydrogen bond that forms an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of...
متن کاملCrystal structure of (E)-2-fluorobenzaldehyde (pyridin-2-yl)hydrazone
The title compound, C12H10FN3, is approximately planar: the dihedral angles between the mean plane of the central N-N=C spacer unit and the fluoro-benzene and pyridine rings are 14.50 (13) and 4.85 (15)°, respectively, while the dihedral angle between the aromatic rings is 16.29 (6)°. The F atom lies at the same side of the mol-ecule as the N atom of the pyridine ring. In the crystal, inversion...
