一、前言 文献报道了醋酸铀酰和一价及二价金属醋酸盐可形成单核、双核和三核络合物。单核络合物有M~+[UO_2Ac_3](M~+为碱金属离子或其他一价阳离子)、H_2[UO_2Ac_4]·2H_2O和M~(2+)[UO_2Ac_4]·nH_2O(M~(2+)为Be~(2+)、Mg~(2+)、Zn~(2+)、Cd~(2+)、Pb~(2+)等);双核络合物有M~(2+)[UO_2Ac_3]_2·nH_2O(M~(2+)为Mg~(2+)、Ca~(2+)、Sr~(2+)、Ba~(2+)、Zn~(2+)、Mn~(2+)、Fe~(2+)、Co~(2+)、和Ni~(2+));三核络合 I. Preface It has been reported in the literature that uranyl acetate and monovalent and divalent metal acetates form mononuclear, binuclear and trinuclear complexes. The mononuclear complexes are characterized by M ~ + [UO_2Ac_3] (M ~ + is an alkali metal ion or other monovalent cation), H_2 [UO_2Ac_4] · 2H_2O and M_ (2 +) [UO_2Ac_4] · nH_2O (2 +), Mg 2+, Zn 2+, Cd 2+, Pb 2+ and so on). The binuclear complexes have M 2+ ) [UO_2Ac_3] _2 · nH_2O (M ~ (2+)) is the dominant species of Mg 2+, Ca 2+, Sr 2+, Ba 2+, Zn 2+, Mn 2+, Fe 2+, Co 2+ and Ni 2+), trinuclear complex
