Preparation, spectroscopic and structural study of copper(II) complexes derived from bulky pyridine ligands Guerrero, Miguel Ayllón, J. A. Calvet Pallàs, Maria Teresa Bardia, Ma. Mercedes Pons, Josefina Coure Estructura cristal·lina (Sòlids) Lligands (Bioquímica) Copper Layer structure (Solids) Ligands (Biochemistry) Three different binuclear tetracarboxylato-bridged copper(II) complexes supported by bulky pyridines ligands [Cu(m-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. 2020-05-31T18:50:13Z 2020-05-31T18:50:13Z 2017-06-08 2020-05-31T18:50:14Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1016/j.poly.2017.06.010 Polyhedron, 2017, vol. 134, p. 107-113 https://doi.org/10.1016/j.poly.2017.06.010 cc-by-nc-nd (c) Elsevier Ltd, 2017 http://creativecommons.org/licenses/by-nc-nd/3.0/es info:eu-repo/semantics/openAccess Elsevier Ltd Articles publicats en revistes (Mineralogia, Petrologia i Geologia Aplicada)
