5-Chloro-benzothia-zole-2-spiro-3'-indolin-2'-one.

ABSTRACT: The title compound, C(14)H(9)ClN(2)OS, crystallizes with two unique mol-ecules, A and B, in the asymmetric unit. The five-membered rings of the benzothia-zole groups in both mol-ecules adopt an envelope conformation [puckering parameters: q(2) = 0.242 (1) Å and ϕ(2) = 217.5 (4)° for A, and q(2) = 0.234 (1) Å and ϕ(2) = 37.7 (4)° for B]. The five-membered rings of the indolinone groups in both mol-ecules are also not planar, with a twisted conformation [puckering parameters are q(2) = 0.112 (2) Å and ϕ(2) = 126.3 (8)° for A, and q(2) = 0.108 (2) Å and ϕ(2) = 306.4 (9)° for B]. In the crystal structure, there are inter-molecular N-H⋯O, N-H⋯S and C-H⋯O hydrogen-bonding inter-actions, forming the layers propagating normal to c.
