Abstract: The title compound, C₂₈H₁₈Cl₂N₄O₄, was prepared by the reaction of phenyl chloroformate and 3,6-bis(4-chlorophenyl)-1,4-dihydro-1,2,4,5-tetrazine. The structural identity, confirmed by crystal structure determination, revealed a re-arrangement, resulting in formation of the 1,2-dihydrotetrazine derivative from the starting materials. The central tetrazine ring adopts a twist conformation.
