摘要 以乙酰丙酮(Hacac)、邻菲咯啉(phen)、硝酸根为配体,8-羟基喹啉为酸度调节剂合成出一个系列的镧系轻稀土四元配合物Ln(NO3)2(phen)2(CH3COCHCOCH3)(Ln=La,Ce,Pr,Nd,Sm)。配合物的结构与性质由元素分析,IR,1HNMR和TGA等表征。单晶Ce(NO3)2(phen)2(CH3COCHCOCH3)·H2O结构经由X射线衍射仪分析表明,晶体属单斜晶系,空间群P21/n,晶胞参数为a=1.11017(8)nm,b=0.98401(7)nm,c=1.34453(10)nm,β=102.0530(10)°,V=1.43641(18)nm3,Dc=1.715g·cm-3,Z=2,F(000)=742。配合物呈单核结构,中心离子Ce髥配位数为10。 A series of quaternary lanthanide complexes Ln(NO3)2(phen)2(CH3COCHCOCH3) (Ln=La, Ce, Pr, Nd, Sm) were synthesized with acetyl acetone (Hacac), 1,10-phenanthroline (phen) and nitrate radical as ligands and 8-hydroxyquinoline as the acidity conditionor. The structure and property of complexes were characterized by elemental analysis, IR, ^1H NMR spectroscopy and TGA, and the single crystal structure of Ce (NO3)2(phen)2 (CH3COCHCOCH3) ·H2O was studied by X-ray diffraction analysis. It is shown that the complex is monoclinic, space group P21/n, a=1.110 17(8) nm, b=0.984 01(7) nm, c=1.344 53(10) nm,β=102.053 0(10)°, V=1.436 41(18) nm^3, Dc=1.715 g· cm^-3, Z=2, F(000)=742. The complex is mononuclear and the coordination number of central ion Ce(Ⅲ) is 10. CCDC: 738798.
