A novel chiral helical coordination complex with Ferroelectric and Weak Ferromagnetic properties

Abstract

A novel chiral copper-based complex constructed from chiral ligand, namely [Cu(L)(H 2 O)]·H 2 O ( 1 ) (L = (S)-3-phenyl-2-(pyrazine-2-carboxamido) propanoic acid). Complex 1 was prepared through solvothermal reactions and characterized by single-crystal X-ray diffraction. Complex 1 crystallizes in the tetragonal system with non-centrosymmetric polar space group P 4 3 and affords one-dimensional (1D) chiral helical chain. Ferroelectric and magnetic studies reveal that 1 shows both ferroelectric and weak ferromagnetic properties. A novel chiral copper-based complex crystallizes in the tetragonal system with non-centrosymmetric polar space group P 4 3 and affords one-dimensional (1D) chiral helical chain. Ferroelectric and magnetic studies reveal that 1 shows both ferroelectric and weak ferromagnetic properties. ► Crystallizes in the tetragonal system with non-centrosymmetric polar space group P 4 3 and affords one-dimensional (1D) chiral helical chain. ► The adjacent helical chains are linked by intermolecular hydrogen bonds, generating a 3D supermolecular network. ► Ferroelectric and magnetic measurements show both ferroelectric and weak ferromagnetic properties.
