The syntheses and crystal structures of two 2,3-diethylnaphthoquinoxaline-6-11-dione derivatives are described. Molecules of C20H16N2O4 (II) are near planar and form stacks down the c axis through π–π ring interactions. In the substituted derivative, C30H34N4O2 (IV), the polycyclic cores have a significant twist and only minor intermolecular C—H⋯O hydrogen-bonding interactions are present.
