COBALT(II), Ni(II), Cu(II), Zn(II), CD(II), Hg(II), U0(2)(VI) AND th(IV) COMPLEXES FROM ONNN SCHIFF BASE LIGAND

A new tetradentate Schiff base, 3-[(Z)-2-piperazin-l-yl-ethylimino]-l, 3-dihydro indol-2-one was synthesized by the condensation of isatin(Indole-2,3-dione) with l-(2-aminoethyl)piperazine(AEP). Its complexes with Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), U0(2)(VI) and Th(IV) have been synthes...
