3-[(2-Formylthiophen-3-yl)(hydroxy)methyl]thiophene-2-carbaldehyde
Abstract
In the title compound, C11H8O3S2, the dihedral angle between the mean planes of the two thiophene rings is 65.10 (10)°. Intramolecular C—H...O interactions form S(6) and S(7) ring motifs. In the crystal, chains along the a axis are formed by C—H...O interactions. Adjacent chains are connected into a three-dimensional network by C—H...O and O—H...O interactions.
