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).
