Copper(II) 2-benzoylbenzoate complexes containing 2-pyridilmethanol and 2-pyridilethanol: Synthesis, crystal structures, spectroscopic, and thermal properties

Two new copper(II) complexes, [Cu(bba)2(pymet)2] 1 and [Cu(bba)2(pyet)2] 2, have been synthesized and characterized by elemental analysis, thermal analysis, UV-Vis, and IR spectroscopic techniques. Single-crystal X-ray analysis of 1 and 2 revealed that the geometries are octahedral. 1 crystallizes in themonoclinic crystal system with space group P21/n, while 2 crystallizes in the triclinic crystal system with the space group P-1. 2-benzoylbenzoic acid ligand behaves as a monodentate, while 2-pyridilmethanol and 2-pyridilethanol ligands act as a bidentate in two complexes. Thermal analysis show that two decomposition stages of the investigated complex 1 and 2, stable up to ∼160° C. Copyright © Taylor & Francis Group, LLC.
