Abstract
The structure of the title compound, methyl (2S,3S)-8-ethenyl-13-ethyl-2,3-dihydro-18-methoxycarbonyl-20-methoxycarbonylmethyl-3,7,12,17-tetramethylporphyrin-2-propionate, C 37 H 42 N 4 O 6 , containing no solvent molecules of crystallization, has been determined at 193 (2) K. The subrings A, B and C of the chlorin macrocycle are approximately in the least-squares plane defined by the four N atoms. The reduced ring D is distorted owing to the steric repulsion between the C17 and C15 substituents. The crystal packing is dominated by π-π interactions between subrings A and C of adjacent molecules in a slipped parallel orientation.
