title: Pyridoxinium picrate.
abstract: The title compound [systematic name: 3-hydroxy-4,5-bis(hydroxymethyl)-2-methylpyridinium 2,4,6-trinitrophenolate], C(8)H(12)NO(3)(+)xC(6)H(2)N(3)O(7)(-), is a complex of picric acid with pyridoxine. The asymmetric part of the unit cell contains one pyridoxinium cation and one picrate anion. The aromatic rings of the picrate anion and the pyridoxinium cation are inclined with a dihedral angle of 83.19 (7) degrees . An intramolecular hydrogen bond between OH and a nearby CH(2)OH group is observed in the cation. The hydrophobic layers at y = {1/2} are packed between the hydrophilic layers at y = 0.
