Abstract
A bidentate NO type Schiff base ligand (L1) has been obtained by the condensation reaction of 4-dimethylaminobenzaldehyde and 2-aminophenol and used as main ligand and l-Alanine as co-ligand (L2), Four novel mixed ligand chelates of composition [M(L1L2)(H2O)2].nH2O, where M represents, Co(II), Ni(II), Cu(II) and Zn(II) ions, in which n= 1, 1.7, 5 and 7 as sited later for chelates. The resulting Schiff base and the mixed ligand chelates were characterized by CHN elemental analysis, molar conductivity, magnetic moment, UV/Vis, IR, 1H-NMR and mass spectra. All the obtained physiochemical data showed an octahedral structures.
