| Abstract: | One new Cu(II) coordination polymer (1) based on 6,6′-dihydroxy-2,2′-bipyridine (H2dhbp) was successfully prepared, with the formula of [Cu(μ2-OH)(Hdhbp)]n (1). Single-crystal X-ray analysis shows that compound 1 crystallizes in orthorhombic chiral space group P212121 and exhibits a left-handed (L) helical [Cu(μ2-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. |
