The title compound, bis[(methyl 8,13-diethyl-2,21,22,2 3-tetrahydro-3,7,12,17-tetramethyl-2 3-oxo-3H-benzo[at]-porphyrin-18-carboxylato-κ4N) zinc (II)], [Zn(C33H34-N4O3)]2, has similar structural characteristics to the naturally occurring factor F430 and forms dimers that are held together by axial interactions between the zinc(II) center and the cyclohexanone carbonyl O atom of a neighboring macrocycle [Zn - O3 2.204 (3) Å]. These dimers form infinite stacks in the crystal stabilized by π-π interactions between the aromatic ring systems.
