Abstract
A new transition metal complexes of Cr(II), Fe(III), Ni(II) and Cu(II) have been synthesized from Mannich base (HL) derived from 3-methyl-4-(p-nitrophenyl)-2-pyrazoline and 5-amino-8-hydroxy quinolone.
The structural features were obtained from their elemental analysis, FT-IR, U.V-Vis spectroscopy, magnetic susceptibility and molar conductance activity. The data show that these complexes have composition of ML2 for Ni(II), Cu(II) and [ML2(H2O)]Cl for Cr(III) and Fe(III) complexes. The U.V-Vis and magnetic moments of the complexes suggest a square planer geometry for Ni(II) and Cu(II), while Cr(III) and Fe(III) were proposed as octahedral geometry.
