摘要
New complexes of isonicotinic acid 2-(9-anthrylmethylene)-hydrazide with Cu(II), Co(II) and Ni(II) have been prepared and characterized by analytical and physico chemical techniques, such as elemental and thermal analyses, magnetic susceptibility and conductivity measurements, and electronic, EPR and IR spectral studies. The infrared spectral studies revealed the bidentate or monodentate nature of the Schiff base in the complexes; the pyridine nitrogen does not participate in the coordination. A tetrahedral geometry is suggested for the nitrate complexes and an octahedral geometry for the others. Thermal studies support the chemical formulation of these complexes.
