1,3-Dibenzyl-1H-anthra[1,2-d]imidazole-2,6,11(3H)-trione.

The mol-ecule of the title compound, C(29)H(20)N(2)O(3), contains four fused rings, three are six-membered rings and one is the five-membered imidazole ring. The fused-ring system is linked to two benzyl groups. The four fused rings are folded around the O=C⋯C=O direction of the anthraquinone, with a dihedral angle of 16.36 (8)° between the two terminal rings (A and D). The imidazole ring (D) is almost perpendicular to the two benzyl groups (E and F) with dihedral angles of 86.69 (17) and 83.15 (13)°, respectively. In the crystal, adjacent mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonding.
