The thiophene ring of the title compound, C22H16Cl2N4O2S, is disordered over two positions, corresponding to rotation of approximately 180 degrees about the single C-C bond, with occupancies approximately in a 4:1 ratio. Weak C-H center dot center dot center dot O hydrogen bonds help in stabilizing the crystal structure.
