Abstract: In the title compound, C11H6N2O {systematic name: 3-(prop-2-yn-1-yloxy)benzene-1,2-dicarbonitrile}, the 14 non-H atoms are approximately coplanar (r.m.s. deviation = 0.051 Å) with the terminal ethyne group being syn with the adjacent cyano residue. In the crystal, centrosymmetric dimers are connected by pairs of C-H...N interactions and these are linked into a supramolecular tape parallel to (1-30) via C-H...N interactions involving the same N atom as acceptor.
