摘 要：<正> Eu（NO3）（TTA）2（TPPO）2 （TTA=thenoyltrifluoroacetone,TPPO=triphenylphosphine oxide）,M=1212.90,triclinic P1,a=1.1081（2）nm,b=1.1857（2）nm,c=1.2580（2）nm,α=65.54（1）°,β=77.91（1）°,γ=61.99（1）°;Z=1,V=1.3281（4）nm3,Dc=1.47g/cm3,μMoKα=14.1 cm-1.The crystal desplaystriboluminescence upon fracture.Structure study shows that the crystal is noncentrosymmetric and no disor-der is found.It is concluded that the polarity of crystals is necessary for the observation of triboluminescence.
