Macrocycle-based metal ion complexation: a study of the lanthanide contraction effect towards hexacyclohexanocucurbit[6]uil†
Abstract
In the present study, the lanthanide(III) contraction effect induced coordination architectures of HCyHQ[6] have been studied. The results, including fifteen crystal structures, indicate that although lanthanide metal ions have similar chemical properties mostly, their slightly different ionic radii play a key role in the formation of different supramolecular
