Two helical one-dimensional copper(II) coordination polymers based on N-(2-hydroxylbenzyl)glycine and N-(2-hydroxylbenzyl)-l-alanine: Syntheses, crystal structures and magnetic studies

Coordination of Cu2+ and N-(2-hydroxylbenzyl)amino acids (H2sgly and H2sala) together with 2,2′-bipyridine as co-ligand led to two new helical coordination polymers. Their crystal structures are similar. But their magnetic behaviors are different; the complex from H2sgly shows ferromagnetic property while that from H2sala displays paramagnetic behavior.
