3-Allyl-1-{[3-(4-nitro-phen-yl)-4,5-dihydro-1,3-oxazol-5-yl]meth-yl}-1H-anthra[1,2-d]imidazole-2,6,11(3H)-trione.

Abstract

The mol-ecular structure of the title compound, C(28)H(20)N(4)O(6), consists of three fused six-membered rings (A,B,C) and one five-membered ring (D). The latter is linked to an isoxazole ring (E) via a methyl-ene unit. A 4-nitro-phenyl substituent (F) is attached to the isoxazole. The fused five and six-membered rings (C,D) are almost coplanar with an r.m.s. deviation of 0.0345 Å and make a dihedral angle of 9.40 (8)° with ring A. The isoxazole and 4-nitro-phenyl rings (E,F) are also almost coplanar with the imidazole and the fused adjacent ring (C,D), forming a dihedral angle of 11.4 (6)°. The crystal packing displays inter-molecular C-H⋯O hydrogen bonding. An intra-molecular C-H⋯O inter-action also occurs.
