Özet
A novel 2D coordination polymer, {[Cu(en) 2][Cu(μ 3-pydc) 2]·6H 2O} n (1) pyridine-2,3-dicarboxylic acid (pydcH 2); ethylenediamine (en), based on the metalloligand [Cu(μ-pydcH) 2] n, has been prepared and characterized by IR, UV-Vis and ESR spectroscopy, thermal analysis, differential scanning calorimetry and single crystal X-ray diffraction techniques. The temperature dependent magnetic properties have also been studied. The pydc ligand exhibits tetradentate-μ 3 bridging mode, being coordinated through three carboxylate oxygens and one nitrogen atom. The complex contains two copper(II) ions that exhibit two different coordination environment with two en and two pydc ligands. The single crystal structure shows that the complex forms a 3D framework with 2D layers along the c-axis. Van der Waals interactions are responsible for the self-assembly of the layer into a 3D network. © 2011 Springer Science+Business Media, LLC.
