(a) C42Cl18 (1); (b) C48Cl18 (2); (c) C60Cl22 (3); (d) C60Cl24 (4); and (e) C96Cl27H3 (5). Front- and side-view representations of the structures of 1–5 are shown. The ORTEP drawings show thermal ellipsoids at a 50% probability level. The carbon and chlorine atoms are represented as grey and green balls, respectively. The peripheral hexagons flip up and down with respect to the inner rings, which are highlighted in blue and red, respectively. The hexagons in 2 and 4, which adopt the twisted configuration, are highlighted in yellow.
