In the title compound, C11H6N2O, the complete molecule is generated by the application of crystallographic twofold symmetry (the molecule is disordered about this axis). The prop-2-yn-1-yl residue is slightly twisted out of the plane of the benzene ring [C-O-C-C torsion angle = 173.1 (3)°] and is orientated away from the nitrile substituents. In the crystal, supramolecular chains along the a axis, arising from C-H⋯N interactions, are connected into stacks along the c axis by π-π interactions between the benzene rings [centroid-centroid distance = 3.6978 (6) Å = length of the c axis].
