In the title zwitterionic mol-ecule, C(11)H(9)N(3)O(4), the imidazole and pyridine rings form a dihedral angle of 2.60 (2)°. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers. Weak inter-molecular C-H⋯O inter-actions further consolidate the crystal packing. ...[more]
