Ethyl 4-(4-chlorophenyl)-5-cyano-2-methyl-6-sulfanylidene-1,6-dihydropyridine-3-carboxylate

In the title compound, C16H13ClN2O2S, the dihedral angle between the 4-chlorophenyl ring and the pyridine ring is 63.53 (6)°. There is an intramolecular C—H...O contact present. In the crystal, molecules are linked by pairs of N—H...S hydrogen bonds, forming inversion dimers. The dimers are linked by C—H...O and C—H...N hydrogen bonds, forming slabs parallel to the ab plane
