Abstract
Abstract Reaction of p-tert-butylcalix[4]arene, 1, with excess ZnEt2 results in complete metallation of the calixarene, or with two equivalents of ZnEt2 selective dimetallation occurs yielding the bis(calix[4]arene) species [{1-H2)Zn}2], 2; distorted four coordinate O-bound zinc centers (Zn-O = 1.896(7) – 1.978(8) A) fuse the slightly flattened cone conformation calixarene units with methylene chloride included in the divergent cavities.
