Aminobenzoic acid 4-methylpyridine/4-methylpyridinium
4-aminobenzoate 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 asin the correction of the positional parameters of the hydrogen atoms that are involved in the O—H...N or N—H...O hydrogen bonds.
