Benzene-1,3,5-tricarboxylic acid–pyridinium-2-olate (1/3)
The asymmetric unit of the title compound, C9H6O6·3C5H5NO, contains one benzene-1,3,5-tri-carb-oxy-lic acid mol-ecule (BTA) and three pyridin-2-ol mol-ecules each present in the zwitterion form. In the crystal, these entities are linked through O-H⋯O(-) and N(+)-H⋯O(-) hydrogen bonds, forming sheets parallel to (10-1). These layers contain macrocyclic rings of composition [BTA]2[pyol]6 and with...

The asymmetric unit of the title compound, C(5)H(5)NO·C(8)H(6)O(4), contains one o-phthalate acid mol-ecule and one pyridin-2-ol mol-ecule, which exists in a zwitterionic form. In the o-phthalate acid mol-ecule, the carboxyl-ate groups are twisted from the benzene ring by dihedral angles of 13.6 (1)° and 73.1 (1)°; the hy-droxy H atom in the latter group is disordered over two positons in a 1:1...

The title compound, 4C(9)H(6)O(6)·C(6)H(8)N(6)·2H(2)O, crystallizes in a layer structure where each sheet is composed of anellated hydrogen-bonded rings of six distinct sizes: R(2) (2)(16), R(3) (3)(18), R(4) (4)(12), R(4) (4)(18), R(4) (4)(22) and R(4) (4)(25). The two largest rings, viz. R(4) (4)(22) and R(4) (4)(25), are associated with O-H⋯N bonds from the carboxyl groups to the triazole ri...
متن کاملDiisopropylammonium 3,5,6-trichloropyridin-2-olate
In the title salt, C(6)H(16)N(+)·C(5)HCl(3)NO(-), the cation links to the anion, which is almost planar, through an N-H⋯O hydrogen bond. Inter-molecular hydrogen bonds link two cations and two anions into a centrosymmetric cluster. The atoms involved in the hydrogen bonding form a planar octa-gonal arrangement in the crystal structure.

Cocrystallization of 4-amino-3,5-bis-(2-pyrid-yl)-1,2,4-triazole (2-bpt) with hemimellitic acid (benzene-1,2,3-tricarboxylic acid) dihydrate (H(3)HMA·2H(2)O) produces the supra-molecular title compound, C(12)H(10)N(6)·C(9)H(6)O(6)·2H(2)O. Inter-molecular N-H⋯N hydrogen bonds are observed between the terminal pyridyl and amino groups of the 2-bpt molecule and the dihedral angles between the cent...
