用硝酸铽与3,5-吡啶二甲酸、邻菲罗啉在水热条件下进行反应, 合成了配合物［Tb(3,5-pdc)(3,5-Hpdc)(H2O)(phen)］n(3,5-H2pdc =3,5-吡啶二甲酸, phen=1,10-邻菲罗啉)。单晶X射线衍射测试表明, 该配合物属单斜晶系, C2/c空间群, 晶胞参数分别为: a=2.734 9(3) nm, b=1.099 48(12) nm, c=2.200 0(3) nm, α=γ= 90°, β=132.147 3(12)°, Z= 8, V=4 904.8(10) nm3。配合物中Tb3+与配体3,5-pdc2-和3,5-Hpdc-交替连接形成了一维链结构, 链与链之间通过邻菲罗啉芳香环的π…π 堆积弱相互作用形成了三维结构。在波长为352 nm的紫外光激发下, 配合物发射出Tb3+的特征荧光。

A terbium complex ［Tb(3,5-pdc)(3,5-Hpdc)(H2O)(phen)］n (3,5-H2pdc=3,5-pyridinedicarboxylic acid, phen=1,10-phenanthroline) was synthesized by reacting terbium nitrate with 3,5-H2pdc and phen at hydrothermal condition. X-ray diffraction analysis of single crystal shows that the complex is crystallized in monoclinic system, C2/c space group. The cell parameters are as follows: a= 2.734 9(3) nm, b=1.099 48(12) nm, c=2.200 0(3) nm, β=132.147 3(12)°, α=γ= 90°, Z=8, V=4.904 8(10) nm3. One-dimensional chain structure is constructed by alternated connection between Tb3+ ions and 3,5-pyridinedicarboxylates for the complex. A three-dimensional coordination polymer is formed by the π…π stacking interaction between the phen ligands. The complex exhibits intense characteristic luminescence of Tb3+ ion under 352 nm excitation.
