A Triple Anion Helicate Assembled from a Bis(biurea) Ligand and Phosphate Ions

Abstract

A word in urea: A strategy of mimicking the scaffold and metal coordination behavior of oligo-2,2′-bipyridine ligands was used to obtain a triple anion helicate from a bis(biurea) receptor and phosphate ions. The successful assembly of the triple helical structure provides guidelines for the design of new anion ligands by taking advantage of the similarities of metal and anion coordination.
