✦ Synopsis
ÁBr À , forms a layered solid with each cation forming three strong and one weaker C-HÁ Á ÁBr hydrogen bonds within the layer. All atoms except two of the methyl H atoms lie on a mirror plane.
Experimental
An aqueous solution of 3-cyano-N-methylpyridinium iodide (Koplitz et al., 2003) was passed down a column of polymer-supported bromide ion exchange resin (Aldrich catalogue No. 51,376-8) and the
