Sarzynski Química IR spectra thermal stability Ni(II) and Cu(II) dimethoxybenzoates magnetic properties of Co(II) The complexes of 2,6-dimethoxybenzoic acid anion with ions of Co(II), Ni(II), and Cu(II)have been synthesized as polycrystalline solids, and characterized by elemental analysis, spectroscopy,magnetic studies, and also by X-ray diffraction and thermogravimetric measurements. The analysedcomplexes have following colours: pink for Co(II), green for Ni(II), and blue for Cu(II) compounds.The carboxylate group binds as monodentate, and bidentate bridging and chelating ligands. On heatingin air to 1173 K the complexes decompose in four, three or two steps. At first, they dehydrate inone or two steps to anhydrous salts, that next decompose to oxides of the respective metals. The solubilityof the investigated dimethoxybenzoates in water at 293 K is of the order of 10-2 mol/dm3. Theirmagnetic moments were determined in the temperature range of 76-303 K. The results reveal the compoundsof Co(II) and Ni(II) to be high-spin complexes and that of Cu(II) to form dimer. 2006 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42931203 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.2 Vol.31 |
