Abstract

A new type of thiophene derivative having alpha- thioketone groups at the 3- and 4- positions, viz. the title compound, C22H20O4S3, has been prepared and studied by NMR spectroscopy and single- crystal X- ray diffraction techniques. The molecule is nearly planar, the dihedral angles between the essentially planar thiophene and benzene rings being 9.4 ( 1) and 10.6 (1)degrees. One of the thioketone O atoms is involved in an intermolecular C - H center dot center dot center dot O hydrogen- bonding interaction.
