Cyclohexane-1,4-dicarboxylic acid–pyridinium-4-olate (1/1)
نویسندگان
چکیده
In the title adduct, C5H5NO·C8H12O4, the heterocycle exists in its zwitterionic form. The cyclo-hexane ring exhibits a chair conformation with the carb-oxy-lic acid groups in equatorial and axial orientations. In the crystal, mol-ecules are linked through charge-assisted O-H⋯O(-), N(+)-H⋯O(-) and N(+)-H⋯O hydrogen bonds, and an additional series of C-H⋯O contacts, giving a pleated two-dimensional hydrogen-bonded network parallel to (-204).

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...

In the title compound, C(16)H(19)FN(3)O(3) (+)·C(8)H(5)O(4) (-)·0.5C(8)H(6)O(4), the benzene-1,4-dicarb-oxy-lic acid mol-ecule is located on a centre of symmetry. In the crystal, the mol-ecules and ions are connected by inter-molecular C-H⋯O and O-H⋯O hydrogen bonds and π-π stacking inter-actions [with a centroid-centroid distance of 3.402 (2) Å], generating a three-dimensional supra-molecular ...

In the crystal structure of the title mol-ecular adduct, C(9)H(7)N·C(8)H(12)O(4), the two species are -linked through a carb-oxy-lic acid-isoquinoline O-H⋯N hydrogen bond. These mol-ecular pairs then inter-associate through the second acid group of the cis-cyclo-hexane-1,2-dicarb-oxy-lic acid molecules, forming a classic centrosymmetric cyclic head-to-head carb-oxy-lic acid-carboxyl O-H⋯O hydro...

The asymmetric unit of the title compound, 2C(6)H(12)N(4)·C(8)H(12)O(4), contains one half-mol-ecule of e,e-trans-cyclo-hexane-1,4-dicarb-oxy-lic acid (the complete molecule being generated by inversion symmetry) and one mol-ecule of hexa-methyl-ene-tetra-mine (HMTA), which are connected by O-H⋯N hydrogen bonds. This forms isolated trimers that pack in a herringbone fashion.
