摘要：

A series of quaternary lanthanide complexes Ln(NO3)(2)(phen)(2)(CHCOCHCOCH3) (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, H-1 NMR spectroscopy and TGA, and the single crystal structure of Ce(NO3)(2)(phen)(2)(CH3COCHCOCH3) center dot H2O was studied by X-ray diffraction analysis. It is shown that the complex is monoclinic, space group P2(1)/n, a=1.110 17(8) nm, b=0.984 01(7) nm, c=1.344 53(10) nm, beta=102.053 0(10)degrees, V=1.43641(18) nm(3), D-c=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.
