摘要
The crystal structure of 5,11,17,23-tetrakis(tert-butyl)-25,27-diethoxypentacyclo[19.3.1.1(3,7).1(9,13).1(15,19)]octa- cosa-1(25),3,5,7(28),9,11,13(27),15,17,19(26),21,23-dodecaene, C48H64O2, has been determined. The calix[4]arene is in the 1,3-alternate conformation. The OH-depleted phenyl rings are more coplanar with the plane of the methylene C atoms than the other two rings. Two phenyl rings show a small boat-like distortion from planarity.
