Construction and interconversion of anion-coordination-based (‘aniono’) grids and double helicates modulated by counter-cations

Abstract

) anion and a bis-tris(urea) ligand. Moreover, the aniono-grid and double helicate motifs can be readily interconverted under ambient conditions by simply changing the counter-cation. These results redefine the power and scope of ACDA, which may represent a new approach in the assembly of well-defined architectures in parallel with the metal coordination-driven assembly of metallo-supramolecules.
