噻吩甲酰基吡唑啉酮缩乙二胺铀(Ⅵ)钍(Ⅳ)配合物的合成及光谱表征

Synthesis and Spectral Characterization of U(Ⅵ) and Th(Ⅳ) Complexes of Thenoylpyrazolone-ethylenediamine

合成了两种新双席夫碱配合物 [UO2 (PMTHP) 2 en]和 [Th(PMTHP) 2 en(NO3) 2 ],其中 (PMTHP) 2 en为N ,N′ 双 [(1 苯基 3 甲基 5 氧 4 吡唑啉基 ) 2 噻吩次甲基 ]乙二亚胺。通过元素分析 ,红外光谱 ,电子光谱 ,核磁共振谱 ,摩尔电导等测试 ,对新配合物的组成、结构和性质进行了表征。

Two novel bis schiff base complexes [UO 2(PMTHP) 2en] and [Th(PMTHP) 2en(NO 3) 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, 13 C 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.
