title: 5-Fluoro-6'H,7'H,8'H-spiro-[indoline-3,7'-pyrano[3,2-c:5,6-c']di-1-benzopyran]-2,6',8'-trione.
abstract: In the title compound, C(26)H(12)FNO(6), the central pyran ring and both benzopyran systems are nonplanar, having total puckering amplitudes of 0.139 (2), 0.050 (1) and 0.112 (2) Å, respectively. The central pyran ring adopts a boat conformation. The crystal structure is stabilized by C-H⋯O, N-H⋯O, N-H⋯F and C-H⋯π inter-actions.
