چکیده
The title mol-ecule, C(28)H(28)Cl(4)N(6)O(6), is built up from four fused rings, viz. two nearly planar imidazole five-membered rings which adopt envelope conformations with the C=O groups at the flap position, and two triazine six-membered rings which adopt chair conformations. Each six-membered ring has a 2,4-dichloro-benzyl substituent attached to an N atom. In the mol-ecule, the two ethyl groups are each disordered between two orientations in 0.784 (16)/0.216 (16) and 0.631 (10)/0.37 (10) ratios. Weak inter-molecular C-H⋯O hydrogen bonds help to stabilize the crystal packing.
