Fluorine-Induced Chiral Coordination Arrays Containing Helical Hydrogen-Bonding Chains of Water or Fluorinated Ligand

Abstract

Two chiral d10 metallosupramolecular systems based on an achiral fluorinated Schiff-base ligand have been prepared and characterized. The ZnII complex 1 reveals 21 helical coordination chains with the inclusion of rare water chains of opposite helix in the perpendicular channels, whereas the CdII complex 2 displays the homochiral 1D coordination motifs with 31 symmetry and a 3D supramolecular architecture built by C–H···F interactions.
