4-Amino-benzoic acid 4-methyl-pyridine/4-methyl-pyridinium 4-amino-benzoate 0.58/0.42: a redetermination from the original data.

ABSTRACT: The title structure, 4-amino-benzoic acid 4-methyl-pyridine/4-methyl-pyridinium 4-amino-benzoate 0.58/0.42, 0.58(C₆H₇N·C₇H₇NO₂)·0.42(C₆H₈N⁺·C₇H₆NO₂^-), has been redetermined from the data published by Kumar et al. (2015 ▸). Acta Cryst. E71, o125-o126. The improvement of the present redetermination consists in the introduction of disorder of the methyl group over two positions as well as in the correction of the positional parameters of the hydrogen atoms that are involved in the O-H⋯N or N-H⋯O hydrogen bonds. After the correction, the hydroxyl hydrogen atom turned out to be disordered over two positions about the centre of the O⋯N bond, whi
