description | Three azo group-containing Schiff base ligands, namely 1-{3-[(3-hydroxy-propylimino)methyl]-4-hydroxyphenylazo}-4-nitrobenzene (<strong>2a</strong>), 1-{3-[(3-hydroxypropyl-imino)methyl]-4-hydroxyphenylazo}-2-chloro-4-nitrobenzene (<strong>2b</strong>) and 1-{3-[(3-hydroxy-propylimino)methyl]-4-hydroxyphenylazo}-4-chloro-3-nitrobenzene (<strong>2c</strong>) were prepared. The ligands were characterized by elemental analysis, FTIR spectroscopy, UV-Vis spectroscopy, <sup>13</sup>C- and <sup>1</sup>H-NMR spectroscopy and thermogravimetric analysis. Next the corresponding copper(II) and cobalt(II) metal complexes were synthesized and characterized by the physicochemical and spectroscopic methods of elemental analysis, FTIR spectroscopy, UV-Vis spectroscopy, magnetic moment measurements, and thermogravimetric analysis (TGA) and (DSC). The room temperature effective magnetic moments of complexes are 1.45, 1.56, 1.62, 2.16, 2.26 and 2.80 B.M. for complexes <strong>3a</strong>, <strong>3b</strong>, <strong>3c</strong>, <strong>4a</strong> <strong>4b</strong>, and <strong>4c</strong>, respectively, indicating that the complexes are paramagnetic with considerable electronic communication between the two metal centers. |
