Abstract
Recent trade is found to be of great interest in structural study of complexes which are derived from organic compounds containing oxygen and nitrogen donar atom. The ligand 3-aminolawoneoxime was synthesized and its complexes with some of the transition metal Fe, Co, Ni, and Cu were prepared by usual method. The complexes of Fe, Co and Ni are found to be paramagnetic while that of copper complex shows diamagnetic behavior. The experimental values of magnetic moments for Fe, Co and Ni complexes when compared with the magnetic moments of Fe, Co and Ni complexes in literature these values are found more close to the values of tetrahedral type of the complexes. The slight lower values of magnetic moment may be attributed to anti ferromagnetic exchange interaction between paramagnetic transition metal ion and the ligand mostly in the semi-quinone form. The observed magnetic moment values for the complexes are closer to the values of tetrahedral type of structures. In copper complex the value lowers to such an extent that it shows diamagnetism probably due to anti ferromagnetic interaction via d-orbitals of two Cu centers present in stacked type square planar structure
