Abstract

In the title mol-ecule, C(22)H(13)Br(2)NO(2), the three benzene rings are arranged in a propeller-like fashion around the central malemide ring, making dihedral angles of 48.2 (4), 30.2 (4) and 34.8 (4)° with the malemide ring. The C-C single-bond lengths connecting benzene groups and maleimide are significantly shorter [C-C = 1.468 (9) and 1.478 (9) Å] than a typical Csp(3)-Csp(3) single bond, indicating partial conjugation between the benzene and the mal-eimide. A weak non-classical C-H⋯O hydrogen bond helps to stabilize the crystal structure.
