Crystal structure of 1-amino-3-(4-chloro-phen-yl)-2-cyano-3<i>H</i>-benzo[4,5]thia-zolo[3,2-<i>a</i>]pyridine-4-carboxamide.

ABSTRACT: In the structure of the title compound, C₁₉H₁₃ClN₄OS, the four atoms of the pyridinic ring that are not fused with the thia-zole, including the sp ³ C atom, lie significantly outside the benzo-thia-zole plane. A short intra-molecular 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 inter-connected layer structures. The first, parallel to the bc plane, involves three classical hydrogen bonds N-H_amine⋯O (one of two), N-H_amine⋯Cl and one N-H_amide ⋯N_cyano; the second, parallel to the ab plane, involves two hydrogen bonds, N-H_amide⋯O and the sec
