Chiral heterocyclic ligands. XVII. Pyridine–amino acid hybrid ligands: synthesis and crystal structures of metal complexes of a chelating ligand derived from L-alanine

A hybrid L-alanine–picolinamide is shown to act as an N,O-chelating ligand upon reaction with copper(II) nitrate and silver(I) perchlorate. X-ray crystal structures reveal that both these chiral complexes further assemble into 1-D polymeric chains through hydrogen bonding associations.
