综述了等网状（相同拓扑）系列金属有机骨架（MOF）的概念和出现情况。我们描述了三种新型 MOF 的制备、表征和晶体结构，它们是已知材料的等网扩张，具有 tbo (Cu-3(4,4',4 ''-(苯-1,3,5-三基-三(苯-4,1-diy1))三苯甲酸酯)(2)、MO F-399) 和 pto 拓扑 (Cu-3(4,4',4) ''-(苯-1,3,5-三基三苯甲酸酯)(2)、Cu-3(4,4',4 ''-(三嗪-2,4,6-三基-(苯-4,1-二基))三苯甲酸酯)(2)、MOF-388)。其中一种材料 (MOF-399) 的晶胞体积比第一个报道的材料大 17 倍。与它等网状，并且具有迄今为止报道的所有MOF中最高的孔隙率（94%）和最低的密度（0.126 g cm(-3)）。
The concept and occurrence of isoreticular (same topology) series of metal organic frameworks (MOFs) is reviewed. We describe the preparation, characterization, and crystal structures of three new MOFs that are isoreticular expansions of known materials with the tbo (Cu-3(4,4',4 ''-(benzene-1,3,5-triyl-tris(benzene-4,1-diy1))tribenzoate)(2), MO F-399) and pto topologies (Cu-3(4,4',4 ''-(benzene-1,3,5-triyltribenzoate)(2), MOF-143; Cu-3(4,4',4 ''-(triazine-2,4,6-triyl-tris-(benzene-4,1-diyl))tribenzoate)(2), MOF-388). One of these materials (MOF-399) has a unit cell volume 17 times larger than that of the first reported material isoreticular to it, and has the highest porosity (94%) and lowest density (0.126 g cm(-3)) of any MOFs reported to date.
