title: [Synthesis and spectral characterization of U(VI) and Th(IV) complexes of thenoylpyrazolone-ethylenediamine].
abstract: Two novel bis-schiff base complexes [UO2 (PMTHP)2en] and [Th(PMTHP)2en(NO3)2] have been synthesized, where (PMTHP)2en = N,N'-bis[(1-phenyl-3-methyl-5-oxo-5-pyrazolinyl)- 2-thenoylmethylidyne] ethylenediamine, and characterized by elemental analysis, IR, UV-Vis, 1H NMR, 13C NMR and molar conductance measurements. The results show that the bis-schiff base is a quadridentate ligand and the nitrate a bidentate ligand, and the uranyl and thorium ions exhibit coordination of six and eight in the complexes, respectively.
