摘要
In the title compound, C17H16N6O2S, an intramolecular N-H center dot center dot center dot O interaction generates an S(6) ring. The pyridine ring makes a dihedral angle of 71.38 (11)degrees with the thiophene ring. In the crystal, molecules are linked by a pair of N-H center dot center dot center dot N hydrogen bonds, forming an inversion dimer. The dimers are stacked in columns along the b axis through weak intermolecular C-H center dot center dot center dot N hydrogen bonds.
