In the title compound, C10H7NO, the dihedral angle between the aromatic ring and the prop-2-yn-1-yloxy grouping is 9.47 (10)°. The bond lengths indicate electronic conjugation between the cyano group, the benzene ring and the propyn-yloxy oxygen atom. In the crystal, a hydrogen bond between the acetylenic C - H atom and the cyano nitrogen atom link the molecules into wave-like [301¯] C(11) chains. These chains are connected by Csp2 - H⋯πacac is the acetylinic C - C triple bond) close contacts [2.794 (1) Å], resulting in a rolling sheet structure parallel to the ac plane and aromatic π-π stacking interactions between the sheets [centroid-centroid distance = 3.593 (2) Å] generate a three-dimensional network.
