✦ Synopsis

Nearly planar molecules of the title compound, C 11 H 11 N 3 O 4 , are linked by O-HÁ Á ÁO hydrogen bonds to form zigzag chains along the c axis; adjacent chains are, in turn, linked by weaker N-HÁ Á ÁO hydrogen bonds to form layers perpendicular to the a axis of the orthorhombic unit cell.
