4-氨基安替吡啉希夫碱与铀酰及溶剂三元配合物的合成及表征

摘要

合成了硝酸铀酰与5-溴水杨醛缩-4-氨基安替吡啉(BsaladppH)和邻香草醛缩-4-氨基安替吡啉(VanadppH)以及2种溶剂(甲醇和乙醇)的4种配合物。通过元素分析、红外光谱、紫外光谱、差热-热重、摩尔电导分析等方法，确定了配合物的组成分别为：UO2(Bsaladpp)LNO3和UO2(Vanadpp)LNO3(L为溶剂甲醇(CH3OH)或乙醇(C2H5OH)。%Four new complexes UO2(Bsaladpp)LNO3 and UO2(Vanadpp)LNO3(BsaladppH=4-(5'-bromosalicylideneimine)-2,3-dimethyl-1-phenyl-3-pyrazoline-5-one, VanadppH=4-(o-vanillalimine)-2,3-dimethyl-1-pheny1-3-pyrazoline-5-one.) have been synthesized and characterized by elemental analysis, IR, UV,DTA-TG and molar conductance. The possible structures of these complexes are proposed.
