Abstract

Cluster's last stand: Six chiral reduced Schiff base ligands containing amino acids and seven LaIII ions self-assemble to form a novel heptameric lanthanum supramolecule with the aid of the CO32− ion (see picture). The cluster exists as a single chiral triple helix. The CO32− ion, which is derived from atmospheric CO2 , adopts a rare μ3-tridentate bridging mode that links three LaIII ions, thus allowing the cluster to efficiently fix CO2.
