description |
There are two crystallograpically independent molecules in the asymmetric unit of the title heteroaryl chalcone derivative, C16H16O4S, with slightly different conformations. The thienyl ring of one molecule is disordered over two positions, with a refined site-occupancy ratio of 0.713 (5):0.287 (5). The molecules are twisted: the dihedral angle between the thienyl and benzene rings is 9.72 (19)° in the ordered molecule, and 3.8 (4) and 2.1 (8)° for the major and minor components, respectively, in the disordered molecule. In both molecules, all three substituted methoxy groups are coplanar with the benzene ring to which they are attached. In each molecule, a weak intramolecular C—H...O interaction generates an S(6) ring motif. In the crystal structure, adjacent molecules are linked into a three-dimensional network by weak C—H...O interactions. |
