Dehydro[24]annulene 1c adopts an unusual planarized conformation in the crystal. A multilayered stack of hydrogen-bonded grids delineates tightly packed nanotubular channels. The related macrocycles 1a and 1b, on the other hand, have the expected puckered conformations in the crystal.

New insights to [18]annulene were gained by looking closer at its X-ray structure, revealing a close face-to-face stacking of 3.16 A in a herringbone-like crystal packing. Hexadehydro[18]annulene was co-crystalized in...
