| Abstract: | p-cumylcalix[8]arene crystallizes with 5 DMSO molecules in the tetragonalspace group P4. The parameters have values: a = b = 17.443(3), c = 9.829(2) Å. Refinement based on 2454 observed reflections led to afinal R value of 0.073. Four dimethylsulfoxide molecules are connected by hydrogenbonds to the calixarene. The macrocycle shows an alternate conformation around the 4 axis. In the network, another DMSO in disordered manner is a foundbetween the calixarenes. |
