Abstract
In the mol-ecule of the title compound, C(20)H(10)BrN(3)O(4)·C(3)H(7)NO, the spiro pyran ring adopts a twist conformation. The indole and coumarin ring systems are each nearly planar, and are oriented at a dihedral angle of 79.29 (3)°. In the crystal structure, inter-molecular N-H⋯O, N-H⋯N, C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules.
