Özet

The title compound, C(14)H(9)ClN(2)OS, crystallizes with two unique molecules, A and B, in the asymmetric unit. The five-membered rings of the benzothiazole groups in both molecules adopt an envelope conformation [puckering parameters: q(2) = 0.242 (1) angstrom and phi(2) = 217.5 (4)degrees for A, and q(2) = 0.234 (1) angstrom and phi(2) = 37.7 (4)degrees for B]. The five-membered rings of the indolinone groups in both molecules are also not planar, with a twisted conformation [puckering parameters are q2 = 0.112 (2) angstrom and phi(2) = 126.3 (8)degrees for A, and q(2) = 0.108 (2) angstrom and phi(2) = 306.4 (9)degrees for B]. In the crystal structure, there are intermolecular N-H center dot center dot center dot O, N-H center dot center dot center dot S and C-H center dot center dot center dot O hydrogen-bonding interactions, forming the layers propagating normal to c.
