Multiple Lanthanide Helicate Clusters and the Effects of Anions on Their Configuration

Abstract

Shaping up your clusters: Two supramolecular clusters of multiple lanthanide helicates have been synthesized. Cluster structure is controlled by the choice of anion, with tetrahedral ClO4− producing larger circular helicates, and trigonal-planar NO3− leading to a compact quadruple-stranded helicate (see picture).
