    • Abstract

       

      A new 1D polymeric copper(II) complex [{Cu(L)$(CF_{3}COO)}2]_{n}$ has been synthesized using apotentially tetradentate Schiff base ligand, HL, ((E)-2-((pyridin-2-yl)methyleneamino)-5-chlorobenzoic acid)and characterized by different spectroscopic methods. Single crystal X-ray structural characterization revealsthat the side arm carboxylate group of the coordinated Schiff base exhibits a $μ_{1,3}$ -bridging mode and connectsthe neighbouring copper(II) ions leading to a zigzag 1D chain structure where the copper(II) ions displaydistorted square pyramidal geometries. Variable temperature magnetic susceptibility measurement reveals aweak antiferromagnetic exchange (J = −0.47±0.01 $cm_{−1}) prevails between copper(II) ions in the chainmediated by the bridging carboxylate group, is also supported by the room temperature EPR spectral study.Electrochemical property of the complex is also reported.
