Triple-stranded helices and zigzag chains of copper(i) 2-ethylimidazolate: solvent polarity-induced supramolecular isomerism

Abstract

The solvent effect of different polarities in hydro(solvo)thermal reaction of Cu(II) and 2-ethylimidazole leads to the generation of two supramolecular isomers of triple-stranded helical and zigzag chain-like structures of Cu(I) 2-ethylimidazolate.
