Abstract: The molecule of the title compound, 2,13-dibenzyl-5,16-dimethyl-2,6,13,17-tetraazatricyclo[16.4.0^1,18.0^7,12]docosane, C₃₄H₅₂N₄, is centrosymmetric. The 14-membered macrocycle adopts the stable trans-III (RRSS) configuration, with one benzyl group above and the other below the macrocycle mean plane. The crystal structure is stabilized by N-HN hydrogen bonds. There is no intermolecular - interaction between benzyl planes, which are almost 6Å apart.
