We present the crystal structure of a coaxially It-stacked discrete dimer of a [12]DBA derivative possessing six peripheral (tert-butoxycarbonypamino groups. The dimer has a significantly short interplanar distance (3.25 angstrom), which is achieved by the sixfold intermolecular hydrogen bonds formed among the peripheral amide moieties. The adjacent dimers are isolated by bulky peripheral tert-butyl groups.
