用水热合成法合成了配合物C24 H16 N7 O9 Sm ，并通过X单晶衍射测定了晶体结构．该配合物是以单核零维分子形式存在，中心离子Sm3＋分别与邻菲啰啉上的氮原子和硝酸根上的氧原子以双齿螯合方式配位，配位数是10．通过红外、紫外、荧光光谱分析及热重分析，表明标题配合物具有良好的热稳定性，在292 cm -1处有一强的紫外吸收峰，在634 nm处的荧光发射峰强度最大，为Sm3＋的4 G5/2→6 H9/2的电荷跃迁的特征发射光谱．

The complex was synthesized by hydrothermal ,and its crystal structure was determined by X-ray diffrac-tion method .It is mononuclear with zero-dimensional molecular form of Sm3+ .The central Sm3+ is connected with four nitrogen atoms of two phen molecules and six oxygen atoms of three nitrate anions ,bidentate chelating mode re-spectively with the coordination number is 10 .The complex was characterized by IR ,UV ,fluorescence analysis and thermogravimetric analysis .The results indicate that the complex has fine thermal stability ,a strong UV absorption peak of 292 cm-1 and the emission peak of 634 nm is the most intensive ,which lies in the transitions from 4 G5/2 to 6 H9/2 of Sm3+ charge transfer .
