LnA_4QH型配合物的合成和性质研究

合成了对甲氧基苯甲酰苯甲酰甲烷(HA),并以其作配体合成了32种未见报道的稀土配合物。其通式为LnA_4QH型混配型配合物(Ln=La～Yb;Q^1=三正丁胺;Q^2=二乙胺;Q^3=六氢吡啶)和LnA_3·xH_2O型配合物。对它们进行了元素分析、摩尔电导、红外光谱、热谱及NMR测定,讨论了镨、铕配合物作为NMR位移试剂的可能性。

Synthesis and Properties of Rare Earth Complexes with p-Methoxybenzoyl-Benzoylmethane and / or Amines

p-Methoxybenzoyl-benzoylmethane(HA)and its complexes LnA_4QH and LnA_3·xH_2O(for Ln=La～ Yb,Q=n-tributyl amine,diethyl amine,hexahydropyridine)were synthesized and characterized by elemental analysis,molar conductivity measurement,infrared spectroscopy,UV-visible absorption spectroscopy,thermal analysis and ~1H NMR spectra.Possibilities of using praseodymium and europium complexes as shift reagent are also discussed.
