The complexes are characterized by the elemental and thermal analyses, molar conductance and magnetic susceptibility ,1HNMR, IR and UV-Vis spectral also were studied. Cr(III), Mn(II), Co(II), Ni(II), Cd(II) and Cu(II) chloride and nitrate complexes have octahedral geometries while Cu(II) acetato complex has distorted octahedral leading to tetragonal geometry. The biological activities of the ligands and complexes have been screened in vitro against some bacteria and fungi to investigate their capacity to inhibit their growth.
