Molecular tectonics: homochiral coordination polymers based on pyridyl-substituted cyclic tetrapeptides

Abstract

Upon combining enantiopure bis-4-pyridylphenyl-substituted cyclotetrapeptides with HgCl₂ and CdCl₂, homochiral 1D zigzag coordination polymers were obtained, while the use of a bis-4-pyridyl-substituted cyclotetrapeptide with HgCl₂ led to the formation of a different type of 1D coordination network.
