Abstract
The two bicyclic fragments of the title compound, C22H20N4O4, are individua lly planar and are turned with respect to each other by 77.8 (2)degrees. Th e formation of intramolecular O-H ... O and N-H ... O hydrogen bonds causes considerable changes in the bond lengths within the amidopyridine fragment .
