Hexa-cata-hexabenzocoronene (hexabenzo[''a'',''d'',''g'',''j'',''m'',''p'']coronene) is a polycyclic aromatic hydrocarbon with the molecular formula C48H24. It consists of a central coronene molecule, with an additional benzene ring fused onto each ring around the periphery.
Hexa-cata-hexabenzocoronene has a contorted structure due to steric crowding among the benzene rings around the edge,[1] analogous to the situation in benzo[''c'']phenanthrene.
