Crystal structure of 3-bromo-2-hy-droxy-benzoic acid.

ABSTRACT: Mutual carbox-yl-carboxyl O-H?O hydrogen bonds link the mol-ecules of the title compound, C7H5BrO3, into centrosymmetric dimers which display a central R 2 (2)(8) ring motif. In addition, there is an intra-molecular hydrox-yl-carboxyl O-H?O inter-action present. A comparison with the crystal structures of 59 other substituted derivatives of salicylic acid shows that both the centrosymmetric carbox-yl-carboxyl O-H?O dimer and the stacking mode of mol-ecules along the short a axis observed in the title structure are frequent packing motifs in this set.

Crystal structure of 4-benzamido-2-hy-droxy-benzoic acid.

Project description:In the title compound, C14H11NO4, the dihedral angle between the mean planes of the aromatic rings is 3.96 (12)° and an intra-molecular O-H⋯O hydrogen bond closes an S(6) ring. A short intra-molecular C-H⋯O contact is also seen. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(8) loops. Conversely, the N-H group does not form a hydrogen bond. Aromatic π-π inter-actions exist at a centroid-centroid distance of 3.8423 (15) Å between the benzene rings. An extremely weak C-H⋯π inter-action also is present.

2-Amino-5-bromo-pyridine-4-hy-droxy-benzoic acid (1/1).

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. In the crystal, mol-ecules are linked to form extended chains along [100] by N-H?O, O-H?O, O-H?N and C-H?O hydrogen bonds. Adjacent chains are crosslinked via further N-H?O inter-actions into sheets lying parallel to (001). The crystal studied was an inversion twin with a 0.54?(2):0.46?(2) domain ratio.

Crystal structure of 3-bromo-2-hy-droxy-benzo-nitrile.

Project description:The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial mol-ecular packing disorder such that a 180° rotation of the mol-ecule about the phenol C-O bond results in disorder of the bromine and nitrile groups. The disorder has been parameterized as a disorder of only the bromine and nitrile substituents on a unique phenol ring. An intra-molecular O-H⋯Br contact occurs. In the crystal, O-H⋯Br/O-H⋯Nnitrile hydrogen bonding is present between the disordered bromine and nitrile substituents and the phenol group, forming a spiral chain about a twofold screw axis extending parallel to the b-axis direction. Within this spiral chain, the mol-ecules also inter-act, forming offset face-to-face π-stacking inter-actions with plane-to-centroid distance of 3.487 (1) Å.

Crystal structure of 4-[(2-hy-droxy-3-meth-oxy-benz-yl)amino]-benzoic acid hemihydrate.

Project description:In the crystal of the title vanilline derivative, 2C15H15NO4·H2O, the secondary amine mol-ecule is accompanied by half equivalent of water. The mol-ecule is non-planar, with torsion angle Car-yl-CH2-NH-Car-yl of -83.9?(2)°. In the crystal, the system of O-H?O hydrogen bonds, including bridging water mol-ecules residing on crystallographic twofold axes, results in a two-dimensional layered structure. Within the layers, there are also weak N-H?? inter-actions involving the vanilline benzene ring.

Crystal structure of 4-(3-carb-oxy-pro-pan-amido)-2-hy-droxy-benzoic acid mono-hydrate.

Project description:In the title hydrate, C11H11NO6·H2O, the organic mol-ecule is approximately planar (r.m.s. deviation for the non-H atoms = 0.129?Å) and an intra-molecular O-H?O hydrogen bond closes an S(6) ring. In the crystal, the benzoic acid group participates in an O-H?O hydrogen bond to the water mol-ecule and accepts a similar bond from another water mol-ecule. The other -CO2H group forms a carb-oxy-lic acid inversion dimer, thereby forming an R 2 (2)(8) loop. These bonds, along with N-H?O and C-H?O inter-actions, generate a three-dimensional network.

5-Chloro-2-hy-droxy-benzoic acid.

Project description:The asymmetric unit of the title compound, C(7)H(5)ClO(3), contains two mol-ecules; both feature an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, both mol-ecules form inversion dimers linked by pairs of O-H⋯O hydrogen bonds with R(2) (2)(8) ring motifs. The dimers are inter-linked by C-H⋯O inter-actions.

Crystal structure of 4-[1-(2-hy-droxy-prop-yl)-4,5-diphenyl-1H-imidazol-2-yl]benzoic acid.

Project description:In the title compound, C25H22N2O3, the central imidazole ring makes dihedral angles of 48.43?(10), 20.23?(10) and 75.38?(11)° with the benzene ring and the two phenyl rings, respectively. The phenyl ring adjacent to the N-bonded 2-hy-droxy-propyl group shows the greatest twist, presumably to minimize steric inter-actions. In the crystal, mol-ecules are linked by O-H?N, O-H?O and C-H?O hydrogen bonds, forming a three-dimensional network. In addition, C-H?? inter-actions are also observed.

3,4-Di-fluoro-2-hy-droxy-benzoic acid.

Project description:In the title compound, C7H4F2O3, an intra-molecular O-H?O hydrogen bond is observed. In the crystal, inversion dimers linked by pairs of O-H?O hydrogen bonds generate R 2 (2)(8) ring motifs. These dimers are linked by C-H?O and C-H?F hydrogen bonds, forming sheets lying parallel to (30-1). The sheets are linked by aromatic ?-? stacking inter-actions [inter-centroid distance = 3.7817?(9)?Å], forming a three-dimensional structure.

In the crystal, O-H⋯O and N-H⋯O hydrogen-bonding inter-actions between the amine mol-ecules and the two types of solvent mol-ecule result in the formation of a layered structure extending parallel to (010).

1H-Benzotriazole-4-hy-droxy-benzoic acid (1/1).

Project description:The asymmetric unit of the title compound, C6H5N3·C7H6O3, comprises independent benzotriazole and 4-hydroxybenzoic acid molecules.

The mean plane of the carb-oxyl group is twisted at an angle of 18.55?(1)° with respect to the benzene ring. The crystal structure is stabilized by weak inter-molecular N-H?N, O-H?N, O-H?O and C-H?O inter-actions, forming a three-dimensional network.
