Abstract
The research includes preparation and study of twenty-one new complexes for some transition elements such as Co (II), Ni (II), Cu (II) and some non-transition elements Zn (II), Cd (II) with the amide ligand 2-hydroxy phthalic acid (L1) derived from the condensation of phthalic anhydride with 2-aminophenol. These prepared complexes were studied and characterized using the following physical and spectral methods: Micro elemental analysis of the elements (C, H, N), molar electrical conductivity, magnetic susceptibility, infrared and electronic spectrum. The complexes were prepared in the base and neutral medium, and the binuclear complexes were prepared by reacting the prepared complexes with the halides of Cobalt (II), Nickel (II) and Copper (II). The results showed that the method of bonding metals with the ligand depends on several basic points, including the environment used in the reaction, as well as the type of metal and the type of substituted groups such as the carboxyl group (COO), OH-phenolic and –NH₂ group.
