Abstract. Two bis-triazole-bis-amide-based copper(II) pyridine-2,3-dicarboxylate coordination polymers (CPs), [Cu(2,3-pydc)(dtb)_0.5(DMF)]·2H₂O (1) and [Cu(2,3-pydc)(dth)_0.5(DMF)]·2H₂O (2) (2,3-H₂pydc = pyridine-2,3-dicarboxylic acid, dtb = N,N′-bis(4H-1,2,4-triazole)butanamide, and dth = N,N′-bis(4H-1,2,4-triazole)hexanamide), were synthesized under solvothermal conditions. CPs 1 and 2 show similar two-dimensional (2D) structures. In 1, the 2,3-pydc anions bridge the Cu^II ions into a one-dimensional (1D) chain. Such 1D chains are linked by the dtb ligands to form a 2D layer. The adjacent 2D layers are extended into a three-dimensional (3D) supramolecular architecture by hydrogen-bonding interactions. The electrochemical properties of 1 and 2 were investigated.
