Abstract

All the non-H atoms of the title compound, C(10)H(10)N(4)O(3), are almost coplanar, the maximum deviation from planarity being 0.065 (3) angstrom. The dihedral angle between the aromatic rings is 1.66 (6)degrees. The molecule adopts the enol-imine tautomeric form with an intramolecular hydrogen-bonding interaction between the Schiff base N atom and the hydroxy group. In the crystal, intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network.
