• The crystal structure of caulerpin (di­methyl 6,13‐di­hydro­dibenzo­[b,i]­phenazine‐5,12‐di­carboxyl­ate, C24H18N2O4), an indole alkaloid, reported in space group Cc with an acute β angle, has been redetermined in the correct space group, C2/c. The mol­ecule has twofold crystallographic symmetry and is composed of two essentially planar indole groups fused to an eight‐membered cyclo­octatetraene ring which adopts a boat conformation. The molecular dimensions are normal. The structure is stabilized by intermolecular and intramolecular interactions involving the indole N—H atom and carbonyl O atom [N⋯O 3.211 (4) and 2.836 (4) Å].
