title: 1-(Anthracen-1-yl)pyrrolidine-2,5-dione.
abstract: In the mol-ecular structure of title compound, C(18)H(13)NO(2), the succinimide ring is orientated away from the plane of the anthracene moiety by 71.94 (4)°. The crystal structure features three different types of inter-molecular inter-actions, viz. C-H⋯O, C-H⋯π and π-π bonds. Mol-ecules along the b axis stack on each other as a result of π-π inter-actions which have a centroid-centroid distance of 3.6780 (15) Å, while C-H⋯π inter-actions are present between neigbouring stacks. Also, acting between the stacks are the C-H⋯O inter-actions between the aromatic H atoms of the anthracene and the O atoms of the succinimide.
