Synthesis, Crystal Structure, and Magnetic Properties of Cu(II) Coordination Polymer with N-3-Pyridine Sulfonyl Amino Acid and 1,10-Phen

Abstract

The title compound [Cu(L)(1,10-phen)]·2H₂O (1) (L = N-3-pyridine sulfonyl amino acid) has been synthesized and characterized by IR, elemental analysis, X-ray diffraction analysis, and magnetic property analysis. The crystal of the complex belongs to the monoclinic space group P2₁/n. In 1, the Cu(II) ion adopts a slightly distorted five-coordinated square pyramid geometry. The L²⁻ ligand adopts N of pyridine and N, O of the amino acids bridging adjacent Cu(II) unit, to form an infinite chain structure along (b) axis direction. Also, abundant O‒H ··· O hydrogen bonds between the adjacent chains and π-π stacking interactions between the adjacent planes expanded the 1-D structure to 3-D supermolecular structure. In addition, magnetic property of 1 has been discussed.
