摘　　要：通过使用柔韧的六齿羧酸配体1,3,5-三嗪-2,4,6-三胺基五二乙酸(H6ttha)溶剂热法制备的一个三维镧系金属有机架构[Tb(ttha)(H2O)4].9H2O(1)。同时,醋酸钠在形成1的反应系统中起着导向作用。化合物1有一个新的三维框架,建立在一维角共享三角十二面体TbO8和列π-π堆叠ttha阵列。在室温下,1的细窄的波段性质是典型的Tb(III)离子。A 3 D lanthanide metal organic framework [Tb（ttha）（HO2）4]·9H2O（1） was prepared solvothermally by using the flexible hexatopic ligand 1,3,5 - Triazine - 2,4,6 - triamine hexaacetic acid （ H6ttha）. The addition of sodium acetate in the reaction system played a structure -directing role in the formation of 1. Compound 1 had a novel three - dimensional framework, built upon one - dimensional comer - sharing trigonal dodecahedra TbO8 and columns of π-π stacking ttha arrays. 1 exhibited intense, narrow photoluminescence upon excitation at room temperature, typical of Tb （Ⅲ） ions.
