Bis[anhydro-meso-rhodochlorinato XV methyl ester)zinc(II)]

Abstract

The title compound bis[(methyl 8,13-diethyl-2,21,22,23-tetrahydro- 3,7,12,17-tetramethyl-23-oxo-3H-benzo[at]porphyrin-18-carboxylato-Kappa4N)- zinc(II)], [Zn(C33H34N4O3)]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) ?]. These dimers form infinite stacks in the crystal stabilized by pi - pi interactions between the aromatic ring systems.
