5-Chloro-spiro-[indoline-3,7'-6H,7H,8H-pyrano[3,2-c:5,6-c']di[1]benzopyran]-2,6',8'-trione.

ABSTRACT: The asymmetric unit of the title compound, C(26)H(12)ClNO(6), consists of two independent mol-ecules. The central pyran rings and both the 1-benzopyran ring systems are nearly planar in both mol-ecules [r.m.s. deviations of pyan rings = 0.0264 (1) and 0.0326 (1) Å for molecules A and B, respectively; r.m.s. deviations of benzopyran rings = 0.0439 (1) and 0.0105 (1) for molecule A, 0.0146 (1) and 0.0262 (1) Å for molecule B]. In the crystal, the molecules are linked by C-H⋯O, N-H⋯O and C-H⋯π inter-actions.
