✦ Synopsis
Abstract
The antimony analogue of choline bromide, [Me~3~SbCH~2~CH~2~OH]Br (1), is formed by the reaction of Me~3~Sb with BrCH~2~CH~2~OH. Crystals of (Me~3~SbCH~2~COO)~8~(NaBr)~7~(MeOH)~9~(H~2~O) (2) are obtained from [Me~3~SbCH~2~COOH]Br and Na~2~CO~3~ in methanol. Crystals of 1 contain stibonium cations with intramolecular coordination of the ethanolic group. The structure of 2 features supramolecular units where the carboxylic groups of stiba betaine molecules are in bridging positions between sodium ions. Copyright © 2005 John Wiley & Sons, Ltd.
