SYNTHESIS OF TRIPODAL BORATE LIGAND WITH NI(II) AND CU(II) COMPLEXES

New tripodal ligand sodium[2,2',2''-((λ4-boranetriyl)tris(1 H-indole-1,3-diyl))tri acetic acid]hydrate (BIAA) was synthesized by the reaction of heteroauxin (indole -3- acetic acid) with sodium tetrahydroborate in 3:1 mole ratio. The ligand was characterized by elemental analysis, spectral studies such as FTIR, UV-Vis., 1HNMR and thermal analysis spectra, the results were agreement with the proposed structure. The coordination property of the ligand was studied through preparation of two metal complexes with Ni(II) and Cu(II) in 2:1 (L:M) mole ratio. Depending on elemental analysis, FTIR , UV-Vis. spectra, magnetic susceptibility measurements , atomic absorption and molar conductivity of metal complexes ,the suggested geometry of nickel and copper complexes were octahedral structures.

Keywords: Tripodal ligands , borate ligands.
