A comparison between the solid state structures and solution behaviour of molecular complexes formed between primary alkylammonium salts and chiral crown ethers incorporating 1,2:4,6-diacetals of D-mannitol

Abstract

The results of an X-ray crystallographic study of D-(1)-Me₂CHNH₃ClO₄ and D-(2)-PhCH₂NH₃CIO₄ reveal conformational features and a hydrogen bonding pattern in the 1:1 complexes which may be correlated with the complexaton behaviour of the 20-crown-6 derivatives D-(1), D-(2), and (3) in solution towards a range of cationic guest species.
