5-Fluoro-isophthalic acid.

ABSTRACT: In the crystal structure of the title compound, C(8)H(5)FO(4), the complete molecule is generated by crystallographic twofold symmetry with two C atoms and the F atom lying on the axis. The mol-ecule is almost planar with the carboxyl group twisted with respect to the mean plane of the benzene ring by a dihedral angle of 2.01?(1)°. In the crystal, inter-molecular O-H?O hydrogen bonds and C-H?F inter-actions connect the mol-ecules into a two-dimensional supra-molecular array.

4,4'-Bipyridine-5-fluoro-isophthalic acid (1/1).

Project description:Co-crystallization of 5-fluoro-isophthalic acid (H(2)fip) with 4,4'-bipyridine (bipy) leads to the formation of the title compound [(H(2)fip)(bipy)], C(8)H(5)FO(4)·C(10)H(8)N(2), with an acid-base molar ratio of 1:1. The acid and base subunits are arrange alternately in the crystal structure, displaying a wave-like tape motif via inter-molecular O-H⋯N and C-H⋯O hydrogen bonds [carbox-yl-pyridine synthon of R(2) (2)(7) hydrogen-bond notation], which are further combined into a two-dimensional architecture through C-H⋯F inter-actions involving the bipy and H(2)fip mol-ecules.

Di-4-pyridyl sulfide-isophthalic acid (1/1).

Project description:In the heteromolecular title structure, C(10)H(8)N(2)S·C(8)H(6)O(4), the two components are linked by O-H⋯N hydrogen bonds to form a one-dimensional chain.

Di-4-pyridyl disulfide-isophthalic acid (1/1).

Project description:In the title 1:1 cocrystal, C(10)H(8)N(2)S(2)·C(8)H(6)O(4), the asymmetric unit contains an isophthalic acid mol-ecule and a 4,4'-dipyridyl disulfide mol-ecule. The two carboxyl groups of isophthalic acid inter-act with neighbouring 4,4'-dipyridyl disulfide mol-ecules through O-H⋯N hydrogen bonds, forming a one-dimensional zigzag chain. Neighbouring chains are linked to each other via π-π stacking inter-actions between the pyridyl rings of adjacent 4,4'-dipyridyl disulfide mol-ecules [centroid-centroid distance = 3.7346 (6) Å], resulting in a layered motif. The dihedral angle between pyridine rings of 84.13 (7)° and the C-S-S-C torsion angle of 91.95 (1)° confirm the gauche conformation of 4,4'-dipyridyl disulfide.

Crystal structure of 5-[(4-carb-oxy-benz-yl)-oxy]isophthalic acid.

Project description:The mol-ecular shape of the title compound, C16H12O7, is bent around the central CH2-O bond. The two benzene rings are almost perpendicular to one another, making a dihedral angle of 87.78?(7)°. In the crystal, each mol-ecule is linked to three others by three pairs of O-H?O hydrogen bonds, forming undulating sheets parallel to the bc plane and enclosing R 2 (2)(8) ring motifs. The sheets are linked by C-H?O hydrogen bonds and C-H?? inter-actions, forming a three-dimensional network.

Project description:The asymmetric unit of the title compound, 2C18H12O4·C2H6OS·2H2O, consists of four crystallographically independent mol-ecules of 5-(naphthalen-1-yl)isophthalic acid, two dimethyl sulfoxide and four water mol-ecules.

In the crystal, multiple O-H⋯O hydrogen bonds link the water mol-ecules with the carbonyl and sulfoxide groups, giving rise to double ribbons along the b-axis direction.
