Abstract

Abstract: Two multi-component crystal structures comprising a carboxylic acid-functionalized imidazolium zwitterion, a p -sulfonatocalix[4]arene anion and aquated metal ion (Na + or Y 3+ ) with or without an auxiliary component (the 3-methoxyphenyl-triphenylphosphonium cation) are reported. The carboxylic acid-functionalized imidazolium ion binds either as a monodentate or a bidentate ligand depending on the nature of the metal ions, and a bi-layer arrangement prevails in the extended structure regardless of the type of metal ion employed or presence/lack of auxiliary component.
