Abstract

Two Schiff-base ligands (I) naphthofuro-[phenylmethine] carbohydrazone [NPMC] and (II) naphthofruo-[3,4-dimethoxyphenylmethine]carbohydrazone [NDMeOPMC] were prepared by reaction between naphthofuran-2-carbohydrazone and benzaldehyde or 3,4-dihydroxybenzaldehyde, respectively. Both ligands are bidentate by coordinating through carboxy oxygen and azomethine nitrogen atoms. Complexes of the type $MLX_n$ were obtained. where M = Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), $UO_2(II)$ and Th(IV), L = [NPMC] or [NDMeOPMC] and X = $Cl_2$ for Co(II), Cu(II), Ni(II), Zn(II), Cd(II) and Hg(II) complexes, X = $NO_3$, n = 2 for $UO_2(II)$ complexes and X = $NO_3$, n = 4 for Th(IV) complexes. All the complexes and ligands were characterized IR, electronic, $^1H$ NMR, ESR, conductance data and magnetic susceptibility measurements.
