摘要

Reaction in aqueous medium of KReO₄ in methanolic solution of RaaiCH₂Ph (1-benzyl-2-(arylazo)imidazole) (1) in the presence of perchloric acid has isolated brown products of {[1-benzyl-2-(arylazo)imidazolium][ReO₄p>−p>]r border=0 SRC=/images/glyphs/BO0.GIF>H₂O}_n, 2. The structural confirmation has been carried out by the single crystal X-ray diffraction study of {[1-benzyl-2-(phenylazo)imidazolium][ReO₄p>−p>]r border=0 SRC=/images/glyphs/BO0.GIF>H₂O}, 2a. The molecules are polymerized via hydrogen bonding and form cross-linked network.
