Homochiral and heterochiral Mn(ii) coordination frameworks: spontaneous resolution dependent on dipyridyl ligands†
Abstract
An unsymmetric tetracarboxylic ligand collaborates with 4,4′-bipyridine to induce spontaneous resolution to form homochiral 3D coordination frameworks, while the use of longer dipyridyl ligands instead of 4,4′-bipyridine leads to isoreticular but heterochiral frameworks.
