2-Hydroxy-4-(prop-2-ynyloxy)benzaldehyde
The asymmetric unit of the title compound, C(10)H(8)O(3), contains two independent molecules, both of which are almost planar (r.m.s deviations for all non-H atoms of 0.044 and 0.053 Å). The dihedral angles between the benzene ring and the prop-1-yne group are 3.47 (1) and 3.07 (1)° in the two mol...

Sumario: | The asymmetric unit of the title compound, C(10)H(8)O(3), contains two independent molecules, both of which are almost planar (r.m.s deviations for all non-H atoms of 0.044 and 0.053 Å). The dihedral angles between the benzene ring and the prop-1-yne group are 3.47 (1) and 3.07 (1)° in the two molecules, and the prop-1-yne groups adopt extended conformations. In each molecule, an intramolecular O—H⋯O hydrogen bond involving the OH and aldehyde substituents forms an S(6) ring. In the crystal, molecules are linked into cyclic centrosymmetric dimers via C—H⋯O hydrogen bonds, generating R (2) (2)(14) ring motifs. The crystal structure is further stabilized by aromatic π–π stacking interactions between the benzene rings [centroid–centroid distances = 3.813 (2) and 3.843 (2) Å] |
