Diethyl 2,6-(2,4-dichlorophenyl)-4,8-dioxo-2,3,6,7-tetrahydro-1H,5H-2,3a,4a,6,7a,8a-hexaazacyclopenta[def]fluorene-8b,8c-dicarboxylate

Diethyl 2,6-(2,4-dichlorophenyl)-4,8-dioxo-2,3,6,7-tetrahydro-1H,5H-2,3a,4a,6,7a,8a-hexaazacyclopenta[def]fluorene-8b,8c-dicarboxylate

The title molecule, C28H28Cl4N6O6, 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,...
