Enantioselective Formation of Double and Triple Helicates of Silver(<scp>I</scp>): The Role of Stacking Interactions

Abstract

Despite having ligands with almost identical conformations, the structures of the AgI complexes of 1 and 2 differ significantly: ligand 1 forms a double-helical complex of P chirality, and 2 gives a triple-helical complex (depicted on the right). The reason for the difference appears to be the existence of strong interligand stacking in the latter case.
