Chiral 3D Architectures with Helical Channels Constructed from Polyoxometalate Clusters and Copper–Amino Acid Complexes

A twist to the right, or to the left: Both enantiomers of a new chiral material were synthesized by a rational approach, using enantiopure proline ligands, copper cations, and Keggin polyoxometalate anions as building blocks. The compounds have open-framework structures containing helical channels.
