There are two independent molecules in the asymmetric unit of the title com
pound, C20H12N2O4. The main difference between the independent molecules is
that while one of them is nearly planar, the other has the furyl substitue
nts at 24.1(1) and 16.1(1)degrees to the central furan ring. The near plana
rity of the molecules introduces steric strain and distortions of the exocy
clic bond angles around the central furan ring. Each molecule contains a st
rong intramolecular O-H ... N hydrogen bond.
