摘要：

The solid state structures of the complexes of para-sulphonato-calix-[4]-arene with putrescine, cadaverine, cis-1,2-cyclohexanediamine and spermidine have been determined. Di- or triammonium cations are included in the calix-[4]-arene molecular cavity and are held in place by hydrogen bonds and hydrophobic interactions. In two of the compounds, diammonium cations are present external to the cavity and are clathrated in tubes formed by the para-sulphonato-calix-[4]-arene network. All four structures show the classic bilayer "organic clay" packing arrangement of opposing para-sulphonato-calix-[4]-arene molecules, with either capsules for the linear diammonium cations, or slipped pairs for the bulky cis-cyclohexane diammonium and triammonium cations.
