Abstract
In the title compound, C16H13N3O4, the dihedral angle between the terminal benzene rings is 14.02 (7)°. The carbonyl groups are anti with respect to each other, which facilitates their participation in the formation of supramolecular chains. Each side of the -C(=O)N(H)N(H)C(=O)- residue associates with a centrosymmetrically related molecule, resulting in the formation of essentially flat ten-membered {
O=CNN(H)}2 synthons. The resultant chains are further consolidated in the crystal structure via C-HO contacts.
