中文摘要: |
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/e空间群晶胞参数分别是:a=21.71(5)A,b=10.203(18)A,C:16.08(3)A,B=118.19(11)°,Z=4,Dc=1.630Mg/m3,y=3139(11)A-3。配合物在321nlTI的紫外光的照射下,在616nnl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。 |
英文摘要: |
A new europium(Ⅲ) complex: bis(4,4'-dimethyl-2,2'-bipyridinato)-tris(nitrato-o,o')-europium(Ⅲ) was prepared by the method of solvotherrnal synthesis, and its mononuelear crystal structure was determined by X-ray diffraction. The crystal structure of the title compound crystallized in monoclinic, space group C2/c, with a = 21.71(5) A, b = 10.203(18) A, c = 16.08(3)A, B =118.19(11)°, Z= 4, Dc= 1.630Mg/m3, V= 3139(11)A3. The fluorescent properties show that the eompound may be a candidate of red light material for its strong emission at 616 nm under ultraviolet radiation of 321 nm. |
