Crystal structure of 4-(prop-2-yn-1-yl-oxy)benzo-nitrile.

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 propyn­yloxy 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 [30-1] C(11) chains. These chains are connected by Csp2—H⋯πac (πac is the acetyl­inic C—C triple bond) close contacts [2.794 (1) A], 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) A] generate a three-dimensional network.
