Abstract

The title butterfly-shaped mol­ecule, C11H6N2O2, is folded slightly along the O=C⋯C=O line, the dihedral angle between the two parts being 6.42 (3)°. In the crystal, adjacent mol­ecules are linked through C—H⋯O hydrogen bonds into infinite layers parallel to the ac plane. The layers are further connected into a three-dimensional netweork via π–π inter­actions formed between pairs of anti­parallel arranged mol­ecules, with a centroid–centroid distance between the central six-membered ring and the benzene ring of 3.4349 (9) Å.
