Abstract: The title compound belongs to triclinic system with a space group 1,a=1. 1718 (2)nm,b=1.5670(3)nm,c=1.0002(2)nm;α=99.97(1)°,β=90.13(1)°,γ=98.36(2)°,M=845. 68,V= 1.7889(5)nm3,Z=2,F(000)=848,Dx=1.57g·cm-3,λ(Mo Kα)=0.071069 nm,μ=18. 06 cm-1,T=295K. The structure was solved by heavy-atom method and refined by full-matrix least squares technique for 54 non-hydrogen atoms and anisotropically for 4961 reflections with I>3σ(I). The final Ris 0.040.Center Eu(Ⅲ)ion is octa-coordinated wiht six oxygen atom of three β-NMA molecules and two nitrogen atoms of PHEN, giving the square antiprism with C1 site symmetry for the Eu(Ⅲ)ion.
