The title compound (N-MC) was synthesized as a nitrogen analog of 25,45,65,85-tetra-tert-butyl-1,3,5,7(2,5)-tetraoxadiazola-2,4,6,8(1,3)-tetrabenzenacyclooctaphane (C-MC). The crystal structure of N-MC was investigated by an X-ray crystallographic analysis, and the crystal was characterized by a step-like columnar structure, which is different from the supramolecular nanotube structure of C-MC. The molecular framework and the number of tert-butyl groups affected the molecular arrangement in the crystal.
