Abstract

The title molecule, 25,26,27,28-tetraacetonyloxy-5,11,- 17,23-tetra-tert-butylpentacyclo[19.3.1.13,7.19,13.115,19]- octacosa-1(25),3,5,7(28),9,11,13(27),15,17,19,21,23-dodecaene, has twofold crystallographic symmetry and adopts a distorted cone conformation in the solid state. The orientation of the four aromatic tings is such that two of the rings are almost parallel to each other and the other two almost normal to one another. This conformation precludes a solvent molecule being enclathrated within the cavity.
