title: 3-Amino-4,6-dimethyl-thieno[2,3-b]pyridine-2-carbonitrile.
abstract: The mol-ecule of the title compound, C(10)H(9)N(3)S, is almost planar, with a dihedral angle of 1.38 (4)° between the thio-phene and pyridine rings. In the crystal packing, mol-ecules are linked into layers parallel to the ab plane by inter-molecular N-H⋯N hydrogen bonds and by π⋯π stacking inter-actions involving adjacent pyridine and thio-phene rings with a centroid-centroid distance of 3.537 (3) Å.
