Despite having ligands with almost identical conformations , the structures of the Ag I 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.
