In the title molecule, C 18 H 18 OS 2 , the geometric parameters are normal and the two S atoms are both in an anti arrangement with respect to the carbonyl O atom. The dihedral angle between the thiophene rings is 5.16 (9) .
The structure of the centrosymmetric title compound, C 12 H 10 Cl 2 N 4 , is stabilized by C-ClΓ Γ Γ andinteractions. The C-ClΓ Γ Γ interactions result in a zigzag chain. The ClΓ Γ Γ chains are connected byinteractions and generate ClΓ Γ Γ andinteracting rings. Theinteraction occurs between the pyri
