The crystal structures of two aromatic chain imides, N-(naphthyl)-N-benzyl-9-phenanthylcarboxamide (1) and N-(9-anthrylcarbonyl)-N-{12-[9-anthryl-N-(phenylcarbonyl)carbonylamino]dodecyl}benzamide (2), were examined. In both imides, two aromatic moieties face each other, creating concave-shaped conformations.
