title: 3,7-Dihydr-oxy-3,7-diphenyl-2H,6H-pyrrolo[3,4-f]isoindole-1,5(3H,7H)-dione methanol disolvate.
abstract: The asymmetric unit of the title compound, C(22)H(16)N(2)O(4)·2CH(4)O, contains one half-mol-ecule and a methanol solvent mol-ecule. The aromatic ring is oriented at a dihedral angle of 82.91 (3)° with respect to the planar indole ring systems. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into chains along the b axis.
