Crystal structure of 1-amino-3-(4-chlorophenyl)-2-cyano-3H-benzo[4,5]thiazolo[3,2-a]pyridine-4-carboxamide

In the structure of the title compound, C19H13ClN4OS, the four atoms of the pyridinic ring that are not fused with the thiazole, including the sp3 C atom, lie significantly outside the benzothiazole plane. A short intramolecular S...O contact of 2.5992 (4) Å is observed. The amide NH2 group is plana...

description In the structure of the title compound, C19H13ClN4OS, the four atoms of the pyridinic ring that are not fused with the thiazole, including the sp3 C atom, lie significantly outside the benzothiazole plane. A short intramolecular S...O contact of 2.5992 (4) Å is observed. The amide NH2 group is planar, whereas the amine NH2 group is pyramidalized. The three-dimensional packing involves two interconnected layer structures. The first, parallel to the bc plane, involves three classical hydrogen bonds N—Hamine...O (one of two), N—Hamine...Cl and one N—Hamide ...Ncyano; the second, parallel to the ab plane, involves two hydrogen bonds, N—Hamide...O and the second N—Hamine...O, together with the short and linear contact Ncyano...Cl—C, which may be regarded as a halogen bond.
