摘要 以双四唑胺(H2bta)、NdCl3.6H2O、KOH为原料,用水热法合成了1个一维异核的Nd3+配合物[KNd(bta)2(H2O)6]·H2O。通过X-射线单晶衍射、元素分析、红外光谱对该配合物进行了结构表征。该化合物属于单斜晶系,P21/m空间群。每个Nd3+与2个来自bta2-离子的4个氮原子和5个水分子形成了1个盖帽的四方双锥,通过bta2-和水分子桥联配体把Nd3+和K+连接成一维链状结构,链与链之间通过O-H…N和N-H…O氢键作用形成三维超分子结构。紫外吸收光谱和荧光光谱表征结果显示该配合物的水溶液在292和412 nm表现出双四唑胺的特征吸收峰和荧光发射特征峰。 A heteronuclear complex [KNd(bta)2(H2O)6]·H2O(1) has been synthesized and charactered by X-ray diffraction,elemental analysis,IR spectroscopy.The crystal of 1 is of monoclinic,space group P21/m with a=0.757 6(1) nm,b=1.280 0(0) nm,c=0.997 6(0) nm,β=101.033 0(10)°,V=0.949 5(1) nm3,D=2.139 g·cm-3,Z=2,F(000)=602,Goof=1.056,R1=0.025 0,wR2=0.056 1.Complex 1 shows a new one-dimensional chain structure and further extended into a 3D supramolecular structure through O-H…N and N-H…O intermolecular hydrogen bonding interactions.The aqueous solution of complex 1 shows interesting fluorescent property caused by H2bta ligand at room temperature.
