3-Methoxy-4-(prop-2-yn-1-yloxy)benzaldehyde
Abstract
In the title compound, C11H10O3, the prop-2-yn-1-yl group is inclined to the benzene ring by 69 (7)°. In the crystal, molecules are linked by a pair of C—H...O hydrogen bonds, forming inversion dimers with an R22(12) ring motif. The dimers are linked by a second C—H...O hydrogen bond, forming sheets parallel to the (102) plane. The sheets stack along the c-axis direction with a separation of ca 3.4 Å.
