1-(6-Chloro-1,3-benzothia-zol-2-yl)hydrazine.

Project description:The asymmetric unit of the title compound, C(7)H(6)ClN(3)S, consists of two crystallographically independent mol-ecules (A and B). The dihedral angle between the benzothia-zole ring system and the hydrazine group is 8.71?(6)° in mol-ecule A and 7.16?(6)° in mol-ecule B. The N-N-C-N and N-N-C-S torsion angles involving the hydrazine group are 170.89?(9) and -9.96?(13)°, respectively, in mol-ecule A and 172.50?(9) and -7.43?(13)°, respectively, in mol-ecule B. In the crystal, neighbouring mol-ecules are connected via pairs of N-H?N hydrogen bonds, generating R(2) (2)(8) ring motifs, and are connected further by N-H?N hydrogen bonds into sheets lying parallel to the ab plane. The crystal studied was an inversion twin, the refined ratio of the twin components being 0.50?(3):0.50?(3).

Project description:In the title compound, C(25)H(14)ClN(3)OS(2), the central thio-phene ring [maximum deviation = 0.011 (1) Å] makes dihedral angles of 55.72 (5), 13.36 (5) and 46.77 (4)° with the adjacent chloro-substituted benzene ring, the benzene ring and the 1,3-benzothia-zole ring system [maximum deviation = 0.012 (1) Å], respectively.
