2-(5-Chloro-2-nitrophenylthio)nicotinoyl Chloride

The two aromatic rings in the title compound, C₁₂H₆Cl₂N₂O₃S, form a dihedral angle of 56.7 (1)°. The alkanoyl chloride group lies slightly out of the plane of the aromatic ring with the carbonyl O and alkanoyl Cl atoms lying 0.219 (2) and -0.374 (1) Å, respectively, from the ring. The nitro group deviates from coplanarity with its aromatic ring, displaying a torsion angle along N-C of 34.9 (3)°. The C-S-C angle is 102.85 (9)°. Bond distances C=O and S-C have values of 1.178 (3) Å, and 1.766 (2) and 1.767 (2)°, respectively.
