(Z)-Ethyl 2-cyano-2-{2-[5,6-dimethyl-4-(thio­phen-2-yl)-1H-pyrazolo­[3,4-b]pyridin-3-yl]hydrazinylidene}acetate

摘要

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