4-Nitro-isophthalic acid.

ABSTRACT: In the crystal structure of the title compound, C(8)H(5)NO(6), both carboxyl groups are involved in inter-molecular centrosymmetric cyclic O-H?O hydrogen-bonding associations, which give a zigzag chain structure extending along (2[Formula: see text]1). Weak ?-? stacking inter-actions are also present [minimum ring centroid separation = 3.893?(4)?Å].

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 ?-? 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.
