In the title compound, C16H11NO2·C5H9NO, the dihedral angles between the male-imide and phenyl rings are 34.7 (2) and 64.8 (2)°. In the crystal, the 2,3-di-phenyl-male-imide and 1-methyl-pyrrolidin-2-one mol-ecules form centrosymmetrical dimers via pairs of strong N-H⋯O hydrogen bonds and π-π stacking inter-actions between the two neighboring male-imide rings [centroid-centroid distance = 3.495 (2) Å]. The dimers are further linked by weak C-H⋯O and C-H⋯π hydrogen bonds into a three-dimensional framework.
