Abstract
Schiff base chelates of V(IV), Ni(II) and Cu(II) ions derived from 4-dimethylaminobenzaldehyde with valine (L1) and with tyrosine (L2) were prepared and investigated by using some physical tools, in terms, elemental analyses, molar conductance measurements, thermogravimetric analysis, magnetic moments, infrared, electronic and electron paramagnetic resonance spectroscopies. The CHN elemental analyses showed the formation of 1:1 and 1:2 [M:L] ratios. The molar conductivity measurements revealed that the chelates are non electrolyte in nature. The magnetic moment results showed a paramagnetic phenomenon for all chelates. The infrared spectral data displayed the proper coordination sites of the Schiff bases toward the metal ions. The electronic absorption spectral results showed the proper electronic transitions and the expected chemical structures for the chelates. The electron paramagnetic resonance spectral data exhibited an octahedral geometry structure for V(IV) Ni(II) and Cu(II) chelates with L1 and L2, while a square planar for Cu(II)L2 chelate.
