Synthesis, crystal structure and magnetic properties of 1D chain Cu(II) complex with the single-μ-chloro bridging

Abstract

Using chiral bidentate ligand containing N-donors L RR (−)-4,5 pinene bipyridine, a 1D chain single-μ-chloro bridged Cu(II) complex (CuL RRCl 2) n ( 1) was synthesized in methanol and characterized by X-ray crystallography and magnetic measurements. X-ray analysis shows that 1 crystallizes in space group Pbca of orthorhombic. The structure of 1 is a neutral, one-dimensional infinite chain polymer. The magnetic investigations demonstrate that complex 1 exhibits intrachain Cu(II)–Cu(II) antiferromagnetic coupling with J = −2.276 cm −1.
