One-dimensional helical Cu(II) coordination polymer: Synthesis, structures, and properties

Abstract One new Cu(II) coordination polymer ( 1 ) based on 6,6′-dihydroxy-2,2′-bipyridine (H 2 dhbp) was successfully prepared, with the formula of [Cu( μ 2 -OH)(Hdhbp)] n ( 1 ). Single-crystal X-ray analysis shows that compound 1 crystallizes in orthorhombic chiral space group P 2 1 2 1 2 1 and exhibits a left-handed (L) helical [Cu( μ 2 -OH)] n -chain. Luminescence of 1 exhibits a broad emission around 440 nm, attributing to the metal to ligand charge transfer (MLCT). Magnetic susceptibility shows antiferromagnetic coupling within compound 1 . Cyclic voltammetry (CV) experiments indicate a potential water oxidation electrocatalyst.
