Crystal 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...
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 کامل1-(2-Hydroxy-5-methylphenyl)-3-(3-methylthiophen-2-yl)prop-2-en-1-one
In the structure of the title compound, C(15)H(14)O(2)S, the benzene ring is nearly coplanar with the thio-phene ring. The hydroxy group substituted at C2 position is in an antiperi-planar conformation with respect to the phenyl ring. The crystal structure exhibits weak intramolecular O-H⋯O hydrogen bonding.
متن کاملCrystal structure of (RS)-(4-chlorophenyl)(pyridin-2-yl)methanol
In the title racemic compound, C12H10ClNO, the dihedral angle between the benzene and pyridine rings is 74.34 (6)°. In the crystal, the mol-ecules are linked by O-H⋯N hydrogen bonds, forming zigzag C(5) [001] chains in which alternating R- and S-configuration mol-ecules are related by c-glide symmetry. In addition, inversion-related pairs of mol-ecules are linked into dimers by pairs of weak C-...
متن کاملCrystal structure of 2-(1H-imidazol-4-yl)ethanaminium chloride
The title mol-ecular salt, C5H10N3 (+)·Cl(-), was obtained as by-product in the attempted synthesis of a histamine derivative. The terminal amino group of the starting material is protonated. The Cimidazole-C-C-N(H3)(+) group in the cation is in an anti conformation with a torsion angle of 176.22 (10)°. In the crystal, cations and anions are linked via N-H⋯N and N-H-Cl hydrogen bonds, forming a...
