Crystal structure of N-hy-droxy-quinoline-2-carboxamide monohydrate.

ABSTRACT: The title compound, C10H8N2O2·H2O, consists of an N-hy-droxy-quinoline-2-carboxamide mol-ecule in the keto tautomeric form and a water mol-ecule connected through an O-H⋯O hydrogen bond. The N-hy-droxy-quinoline-2-carboxamide mol-ecule has a nearly planar structure [maximum deviation = 0.062 (1) Å] and only the hy-droxy H atom deviates significantly from the mol-ecule plane. In the crystal, π-π stacking between the aromatic rings [inter-centroid distance = 3.887 (1) Å] and inter-molecular O-H⋯O hydrogen bonds organize the crystal components into columns extending along the b-axis direction.

Crystal structure of N-hy-droxy-picolinamide monohydrate.

Project description:The crystal structure of the title compound, C6H6N2O2·H2O, consists of N-hy-droxy-picolinamide and water mol-ecules connected through O-H⋯O and N-H⋯N hydrogen bonds. The O-H⋯O inter-actions and π-π stacking inter-actions between the pyridine rings [centroid-centroid distance = 3.427 (1) Å] organize the components into columns extending along the b axis and the N-H⋯N hydrogen bonds link these columns into a two-dimensional framework parallel to (100). The N-hy-droxy-picolinamide mol-ecule adopts a strongly flattened conformation and only the O-H group H atom deviates significantly from the mol-ecule best plane. The dihedral angle between the hydroxamic group and the pyridine ring is 5.6 (2)°. The conformation about the hydroxamic group C-N bond is Z and that about the C-C bond between the pyridine and hydroxamic groups is E.

Crystal structure of (E)-4-hy-droxy-N'-(3-hy-droxy-benzyl-idene)benzohydrazide monohydrate.

Project description:In the title benzohydrazide hydrate, C14H12N2O3·H2O, the dihedral angle between the aromatic rings is 58.11 (6)° and the C=O and N-H groups adopt an anti orientation. The main twist in the mol-ecule occurs about the C(=O)-Car (ar = aromatic) bond, with an N-C(=O)-Car-Car torsion angle of -43.5 (2)°. In the crystal, the components are linked by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds. These inter-actions generate [10-1] chains, with adjacent organic mol-ecules linked by inversion symmetry generating either pairs of N-H⋯O links [R 2 (2)(16) loops] or pairs of O-H⋯O links [R 2 (2)(20) loops]. Pairs of water mol-ecules are located in the R 2 (2)(20) loops and form their own O-H⋯O and O-H⋯N hydrogen bonds to adjacent organic mol-ecules in the chain. Finally, an inter-chain O-H⋯O hydrogen-bond link from the 4-hy-droxy group generates (010) sheets.

Crystal structure of 8-hy-droxy-quinoline: a new monoclinic polymorph.

Project description:In an attempt to grow 8-hy-droxy-quinoline-acetamino-phen co-crystals from equimolar amounts of conformers in a chloro-form-ethanol solvent mixture at room temperature, the title compound, C9H7NO, was obtained. The mol-ecule is planar, with the hy-droxy H atom forming an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules form centrosymmetric dimers via two O-H⋯N hydrogen bonds. Thus, the hy-droxy H atoms are involved in bifurcated O-H⋯N hydrogen bonds, leading to the formation of a central planar four-membered N2H2 ring. The dimers are bound by inter-molecular π-π stacking [the shortest C⋯C distance is 3.2997 (17) Å] and C-H⋯π inter-actions into a three-dimensional framework. The crystal grown represents a new monoclinic polymorph in the space group P21/n. The mol-ecular structure of the present monoclinic polymorph is very similar to that of the ortho-rhom-bic polymorph (space group Fdd2) studied previously [Roychowdhury et al. (1978 ▶). Acta Cryst. B34, 1047-1048; Banerjee & Saha (1986 ▶). Acta Cryst. C42, 1408-1411]. The structures of the two polymorphs are distinguished by the different geometries of the hydrogen-bonded dimers, which in the crystal of the ortho-rhom-bic polymorph possess twofold axis symmetry, with the central N2H2 ring adopting a butterfly conformation.

Project description:In the title compound, C13H10BrN3O2·H2O, the conformation about the azomethine double bond is E. The mol-ecule exists in the amido form with a C=O bond length of 1.229 (2) Å. There is an intra-molecular O-H⋯N hydrogen bond forming an S(6) ring motif. The whole mol-ecule is almost planar, with an r.m.s. deviation of 0.021 Å for all non-H atoms, and the dihedral angle between the planes of the pyridine and benzene rings is 0.74 (12)°. In the crystal, the water mol-ecule of crystallization links the organic mol-ecules via Ow-H⋯O, Ow-H⋯N and N-H⋯Ow hydrogen bonds and short C-H⋯Ow contacts, forming sheets lying parallel to (100). Within the sheets there is a weak π-π inter-action involving the pyridine and benzene rings [centroid-to-centroid distance = 3.8473 (15) Å]. The sheets are linked via C-H⋯Br inter-actions, forming a three-dimensional network.

Hirshfeld surface analysis indicates that the most significant contacts in the crystal packing are C⋯H/H⋯C (29.2%), O⋯H/H⋯O (28.6%) and H⋯H (28.5%).
