Abstract

Several new complexes of Cr(III), Mn(II), Fe(II), Co(II) and Cu(II) containing Cyanex 302 [bis(2,4,4-trimethylpentyl) monothiophosphinic acid] were synthesized and characterized by elemental analysis, molar conductance, molecular mass determination, magnetic, UV-Visible and IR studies. The prepared metal complexes has the compositions: 2. [CrL3].H2O, 3. K[MnL3].H2O, 4. [FeL2].H2O, 5. K[CoL3] and 6. K[CuL3].H2O (Where, L means anion of bis(2,4,4-trimethylpentyl) monothiophosphinic acid). The complexes 2, 3, 5 and 6 are assumed to have octahedral geometries, but the complex 4 is tetrahedral based on experimental data. From magnetic measurements all the complexes are found to be paramagnetic. Measured molar conductance showed that the complexes 2 and 4 are non-electrolytes and complexes 3, 5 and 6 are electrolytes. Besides, some metal complexes have shown very good antibacterial and antifungal activities.
