| dc.description.abstract | A new multidentate tripodal ligand 2, 4, 6-tris (N-Salicylidene hydrazino)-s-Triazine (TSHSTZ) was synthesized by nucleophilic substitution reaction between 1-(2-hydroxy benzylidene) hydrazine (HBH) and cyanuric chloride in 3:1 mole ratio. The precursor 1- (2-hydroxy benzylidene) hydrazine (HBH) was prepared in early stage of the ligand preparation by simple shiff base condensation reaction between salicylaldehyde and hydrazine sulfate. The ligand (TSHSTZ) behaves as a dibasic ONN donor towards Ni(II) and tri basic tris-ONN donor towards Zn(II) .The Ni(II) and Zn(II) complexes of the ligand(TSHSTZ) were synthesized by using 1:3 ligand to metal mole ratio in chloroform/Methanol medium. The ligand and complexes were investigated by NMR, IR, UV-Vis and AAS techniques. Furthermore, conductivity and magnetic susceptibility measurements were carried out for the complexes. Ring nitrogen as well as the bridging nitrogen of hydrazine in TSHSTZ were proposed as metal binding centers. The AAS data reveals 1:3 ligand to metal ratio for Zn (II) complex, where as 1:1 ligand to metal ratio for Ni (II) complex. Conductivity measurement tells that both the complexes are nonelectrolytes and Magnetic moment of Ni(2.83B.M) indicates octahedral geometry for Ni(II) complex and NMR data ,in addition to other spectroscopic data together with acetate test and conductance result suggest tetrahedral geometry for Zn(II) complex.
