Abstract:
In the title compound, C10H7NO, the dihedral angle between the aromatic ring and the prop-2-yn-1-yl-oxy 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 acetyl-enic C-H atom and the cyano nitro-gen atom link the mol-ecules into wave-like [30-1] C(11) chains. These chains are connected by Csp (2)-H⋯πac (πac is the acetyl-inic 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 inter-actions between the sheets [centroid-centroid distance = 3.593 (2) Å] generate a three-dimensional network.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
