| Abstract | ||
| A new complexes have been prepared of some transition metal ions (Co(II),Ni(II),Cu(II)) and some non transition metal ions (Zn(II),Cd(II)) with a number of Schiff bases obtained from the condensation of some amino acids (leucine) and (3-acetyl pyridine, 4-acetyl pyridine, acetoacetaanilide). All the prepared complexes have been characterized by elemental analysis, molar conductance, magnetic susceptibility infrared and electronic spectral studies. The complexes were classified as: A-mononuclear complexes. 1- Complexes with the formula [ML(CH3COO)(H2O)2]. 2- Complexes with the formula [ML(CH3COO)]H2O and [ML(H2O)]. B-Di nuclear complexes. 1- Complexes with the formula [M2(L)2(CH3COO)2] .2H2O 2- Complexes with the formula [M2(L)2].2H2O M= Co(II),Ni(II),Cu(II),Zn(II)Cd(II). These studies revealed the action of first and second ligands as neutralbidentate and the third ligands as tridentate ligands in all complexes prepared , formed complexes with tetra-coordinated (tetrahedral or square planer) and hexa-coordinated (octahedral) structure and that all the prepared complexes were non electrolyte. | ||
