4,5‐Bis(phthalimidometh­yl)acridine

The structure of the title symmetrically disubstituted acridine derivative [systematic name: N , N ′‐(acridine‐4,5‐diyldimethyl­ene)bis­phthalimide], C 31 H 19 N 3 O 4 , has been determined at 120 K using synchrotron radiation. The mol­ecule contains a planar acridine and two planar phthalimide fragments. The pseudo‐torsion angle N—C⋯C—N between the phthalimido­methyl groups, where C⋯C is an intra­molecular contact between the methyl­ene C atoms, is 95.9 (2)°; the phthalimide rings are almost parallel to each other.
