2-Amino-5-(4-carboxyl-atophen-yl)-pyridinium monohydrate.

ABSTRACT: The title compound, C(12)H(10)N(2)O(2)·H(2)O, crystallizes as a zwitterion in which the pyridine N atom is protonated and the carb-oxy -OH group is deprotonated. The benzene and pyridinium rings are inclined with a dihedral angle of 6.63?(5)° between them. In the crystal, inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions link adjacent mol-ecules into a two-dimensional double layered supra-molecular network.
