用溶剂热法合成了一种新的单核铕配合物,二(4,4’-二甲基-2,2’-联二吡啶)-三硝酸合铕(Ⅲ),该配合物的晶体属单斜晶系,C2/c空间群晶胞参数分别是:a=21.71(5),b=10.203(18),c=16.08(3),β=118.19(11)°,Z=4,Dc=1.630 Mg/m3,V=3139(11)-3。配合物在321 nm的紫外光的照射下,在616 nm波长处有强的荧光发射,可望成为一种有实用价值的红光材料。
A novel mononuclear europium complex, europium (Ⅲ) bis (4,4’-dimethyl-2,2’-bipyridyl) -tritrate, was synthesized by solvothermal method. The crystal of the complex Is a monoclinic, and the unit cell parameters of C2 / c space group are a = 21.71 (5) , b = 10.203 (18) , c = 16.08 = 4, Dc = 1.630 Mg / m3, V = 3139 (11) -3. Under the irradiation of 321 nm ultraviolet light, the complex has strong fluorescence emission at the wavelength of 616 nm, which is expected to become a kind of red material with practical value.
