| heal.abstract | Ten mixed-ligand Co(II) compounds with 2-hydroxy-benzophenones(ketones) and neocuproine(neoc) were synthesized and characterized by physicochemical and spectral (IR, UV-Vis) data. The cyclic voltammetry study in CH3CN gave all the expected waves for the redox processes of the metal Co(II) and the studied ligands. The X-ray diffraction study of two representative compounds proved the two different geometries, octahedral for [Co(2-hydroxy-benzophenone)2(neoc)] (3) and trigonal bipyramidal for [Co(2-hydroxy-4-methoxybenzophenone)(neoc)Br] (10). Additionally, the precursor compound [Co(neoc)Br2]Β·CH3OHΒ·H2O (11) was proved by (X-ray) to posses tetrahedral geometry. The molecular structure and the possible isomers of the trigonal bipyramidal complex 10 were studied by means of density functional calculations (DFT). The thermal stability was investigated by means of simultaneous TG/DTG-DTA technique in nitrogen atmosphere up to 1000 Β°C, where metallic cobalt was found as the solid residue. | en |
