Abstract

The deprotonation of calix[8]arenes (H8L) with BunLi in DMF followed by reaction with dry SrBr2 yielded the discrete molecular complexes Li4Sr2(H2L)(O2CC4H9)2(dmf[hair space])8 (H8L: 1, p-Pri; 2, p-Bui); the crystal structures of these complexes of hexa-deprotonated calix[8]arenes show that mixed metal, polynuclear, inorganic cores can be formed within the large and flexible cavity of calix[8]arenes.
