摘要：

Tetralithiation of tert-butylcalix[4]arene in the presence of hmpa (hexamethylphosphoramide) results in the isolation of either a monomeric complex in which LiOH is incorporated into an Li5O5 core based on an isolated square pyramid of Li atoms, or a dimeric LiOH-free species containing an Li8O8 core in which the same structural moth is maintained by edge-sharing of two square pyramids of Li atoms.
