5,6-Di-2-thienyl-2,3-dihydropyrazine

Abstract

In the title compound, C12H10N2S2, which was synthesized by the reaction of 2,2′-thenil and ethyl­enediamine, the dihedral angle between the two thio­phene rings is 66.33 (9)°. In the crystal structure, inter­molecular C—H⋯N hydrogen bonds link the mol­ecules into infinite chains along the b axis and weak C—H⋯π inter­actions may further stabilize the structure.
