Abstract O614.7+11; 室温下,以N-乙基吡啶碘盐(Epy)I和四水溴化锰(MnBr2·4H2 O)为原料合成了一种零维发光材料[(Epy)2][MnBr2 I2].对该配合物进行元素含量分析、红外光谱、单晶X射线衍射、粉末X射线衍射、紫外可见吸收光谱、光致发光光谱及X射线激发发射光谱等测试.单晶X射线衍射结果表明:配合物为单斜晶系,C2/c空间群,中心离子Mn(Ⅱ)为四面体构型,晶胞参数为a=2.8255(6)nm,b=0.83971(17)nm,c=1.8360(4)nm.在332 nm紫外光激发下,配合物发出528 nm的绿光,对应于四面体Mn(Ⅱ)配合物的4 T1(G)→6 A1特征辐射跃迁,荧光寿命为58.85μs,荧光量子产率为58.29%.X射线激发光谱表明配合物发光强度较高,具有X射线荧光性能.
