Abstract

© 2017 Elsevier Ltd Three different binuclear tetracarboxylato-bridged copper(II) complexes supported by bulky pyridines ligands [Cu(µ-MeCO2)2(dPy)]2 (dPy = 3-phenylpyridine (1), 2-benzylpyridine (2) and 4-acetylpyridine (3)) have been synthesised. These compounds were obtained from reaction of [Cu(MeCO2)2(H2O)]2 with pyridine-derived ligands in methanol at room temperature. All compounds were fully characterized by analytical and spectroscopic methods. The molecular structures were determined by X-ray diffraction analysis. All compounds consist of binuclear units where both Cu(II) atoms are linked by four syn–syn carboxylates bridges, showing a paddle-wheel unit, and exhibit interesting intermolecular interactions in the outer coordination sphere.
