Ambidentate binding in macrocyclic helicates: towards tuning secondary structure

Chemical Communications Pub Date: 1900-01-01 DOI: 10.1039/CC9960000309

Abstract

X-Ray analysis of new helicates of CdII and PbII derived from a tetraimine macrocyclic ligand shows that the compression of the double-helical array as the size of the metal ion increases corresponds with a change in coordination mode of the ligand.
