Abstract : The following complexes were prepared and their magnetic properties at room temperature and Uv and visible absorption spectra were studied: 4-Nitroquinoline N-oxide copper(II) chloride; Bis-4-nitroquinoline N-oxide copper(II)chloride; 3-Methylpyridine N-oxide copper(II) chloride; 4-Methylpyridine N-oxide copper(II) chloride; 4-Chloropyridine N-oxide copper(II) chloride; 4-Hydroxypyridine N-oxide copper(II) chloride; 2, 6-Dimethylpyridine N-oxide copper(II) chloride. The 8-hydroxy-2-methylquinoline, salicylaldehyde and acetylacetone ligands have similar functional groups and produce compounds with the same empirical formula under the same reaction condition. However, for Cu(AcAc)C1 different magnetic properties are observed. It is postulated that in Cu(AcAc)C1 a chloridebridged structure exists, whereas the others seem to have the oxygen bridged structure .
