4-(Prop-2-yn-1-yl­oxy)benzene-1,2-dicarbonitrile

In the title compound, C(11)H(6)N(2)O, 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].
