Abstract

The title compound, C50H60O6, is a new p-tert-butylcalix[4]arene derivative, adopting a 1,3-alternate conformation, with the complete molecule generated by twofold rotation symmetry. In the crystal structure, the molecules associate into layers in the ac plane. The three methyl groups of one tertbutyl group are disordered over two positions with site-occupancy factors approximately in the ratio 3:1.
