A novel Eu( Ⅲ ) complex(1) was synthesized by reaction of trans-4-[p-( N, N-diethylamine) styryl]-N-methylpyridinium iodide with europium( Ⅲ )-thenoyltrifluoroacetonato moiety. The structure was characterized by 1 H NMR and X-ray single-crystal diffraction. 1 belongs to monoclinic system, space group P21/c with α = 10. 543(5)(A), b =22. 653(5)(A), c =26. 053(5)(A), β =113.272(5)°, V=5716.0(3) (A)3, Dc=1.515 g· cm-3, Z=4, F(000) =260 8,μ=1.333 mm-1. The final R1 indice was 0.066 9.%通过反式4-[4'-(N,N-二乙基胺)苯乙烯基]-N-甲基吡啶碘盐与β-二酮稀土化合物反应,合成了一种新型的Eu(Ⅲ)配合物(1),其结构经JH NMR和单晶X-射线衍射表征.1属单斜晶系,P21/c空间群,晶胞参数a=10.543(5)A,b=22.653(5) A,c=26.053(5)A,β=113.272(5)°,V=5716.0(3)A3,Dc=1.515g·cm-3,2=4,F(000)=2608,μ=1.333 mm-1,最终偏离因子Ri=0.0669.
