N'-Hy-droxy-pyridine-2-carboximidamide.

Project description:The title mol-ecule, C6H7N3O, is almost planar (r.m.s. deviation = 0.0068?Å) and adopts an E conformation about the C=N double bond. In the crystal, mol-ecules are linked by pairs of strong N-H?N hydrogen bonds, forming inversion dimers with R 2 (2)(10) motifs. The dimers are further linked into C(3) chains through O-H?N hydrogen bonds.

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

Project description: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.

2-Bromo-3-hy-droxy-6-methyl-pyridine.

Project description:In the title compound, C6H6BrNO, the Br atom is displaced from the pyridine ring mean plane by 0.0948?(3)?Å, while the hydroxyl O atom and the methyl C atom are displaced by 0.0173?(19) and 0.015?(3)?Å, respectively. In the crystal, mol-ecules are linked via O-H?N hydrogen bonds, forming chains propagating along the a-axis direction. These chains are linked by C-H?Br hydrogen bonds, forming corrugated two-dimensional networks lying parallel to the ac plane.

rac-6-Hy-droxy-2,5,7,8-tetra-methyl-chroman-2-carboxamide from synchrotron data.

Project description:The crystal structure of the title water-soluble analogue of vitamin E, trolox amide, C(14)H(19)NO(3), solved and refined against synchrotron diffraction data, contains two mol-ecules in the asymmetric unit. In both molecules, the heterocyclic ring is in a half-chair conformation. The crystal packing features a herring-bone pattern generated by N-H?O hydrogen bonds between the hy-droxy and amide groups. O-H?O hydrogen bonds also occur.

2-Amino-5-methyl-pyridinium 3-hy-droxy-pyridine-2-carboxyl-ate.

Project description:In the 3-hy-droxy-picolinate anion of the title salt, C6H9N2 (+)·C6H4NO3 (-), an intra-molecular O-H?O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar, with a dihedral angle of 9.55?(9)° between the pyridine ring and the carboxyl-ate group. In the crystal, the cations and anions are linked via N-H?O hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R 2 (2)(8) and R 4 (2)(8) ring motifs. The crystal structure also features N-H?N and weak C-H?? inter-actions.

Project description:The title 1:1 adduct, C(5)H(5)BrN(2)·C(7)H(6)O(3), contains two mol-ecules of each species in the asymmetric unit, with similar geometries.

Project description:In the title compound, [Cu(C(7)H(5)O(3))(2)(C(5)H(5)N)(2)], the Cu atom is located on an inversion center and is coordinated by the N atoms of the two pyridine ligands, trans to each other, and to the carboxyl-ate O atoms of two bidentate 4-hy-droxy-benzoate ligands [Cu-O = 1.9706 (10) and 2.5204 (11) Å]. Hydrogen bonding between hy-droxy H and carboxyl-ate O atoms results in a layer structure parallel to the ab plane.

?-4,4'-Bipyridine-bis-[aqua-(4-hy-droxy-pyridine-2,6-dicarboxyl-ato)copper(II)].

Project description:The title compound, [Cu(2)(C(7)H(3)NO(5))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a centrosymmetric binuclear molecule. Each completely deprotonated 4-hy-droxy-pyridine-2,6-dicarb-oxy-lic acid mol-ecule assumes a tridentate chelating coordination mode. The square-pyramidal coordination geometry around the Cu(II) ion is completed by the bridging bipyridine ligand and an apical water molecule. Adjacent complexes are connected via O-H?O and C-H?O hydrogen bonds to generate a three-dimensional supra-molecular structure.
