المستخلص:
The work covered the preparation of two new azo ligands, prepared the ligands (CAAP) and (TAAP) by coupling with the diazonium salt of the compound (4 - amino antipyrine) in 5% basic media.The prepared ligends were identified through techniques (FTIR, elementary analysis, UV - Visible and mass spectra).Conducted spectral study of a wide solvents three of the ions transition metals (Co (II), Ni (II), Cu (II)) where he was appointed the optimal conditions for concentration (that obey beers - lambert law) and pH values enhanced ranged acidic functions of these solutions (7 - 9.5), And has benefit from that study for the purpose of spectral appoint molar ratios of the complexes to be prepared and the molar ratio was (1 : 2) for all the complexes prepared and both ligand two ways molar ratios and continuous variations.The preparation of complexes of new azo ligand was sure to complete the preparation by FTIR spectroscopy , elementary analysis and atomic absorption. Electrical molar conductivity results showed that the complex ionic (1 : 1) and using three solvents (DMF, DMSO, EtOH).Magnetic susceptibility data agreed with the present of (three odd electrons for cobalt(II) complexes, two odd electron for nickel(II) complexes & odd electron for copper(II) complexes)According to the results of the study combined could suggest the octahedral geometric and the presence of one coordination water molecule coordination sphere inside.
