Benzene-1,2-dicarboxylic acid–pyridinium-2-olate (1/1)
The asymmetric unit of the title compound, C(5)H(5)NO·C(8)H(6)O(4), contains one o-phthalate acid molecule and one pyridin-2-ol molecule, which exists in a zwitterionic form. In the o-phthalate acid molecule, the carboxylate groups are twisted from the benzene ring by dihedral angles of 13.6 (1)...

| description | The asymmetric unit of the title compound, C(5)H(5)NO·C(8)H(6)O(4), contains one o-phthalate acid molecule and one pyridin-2-ol molecule, which exists in a zwitterionic form. In the o-phthalate acid molecule, the carboxylate groups are twisted from the benzene ring by dihedral angles of 13.6 (1)° and 73.1 (1)°; the hydroxy H atom in the latter group is disordered over two positons in a 1:1 ratio. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the molecules into zigzag chains in [-101]. |
