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-diyl))tribenzoate)(2), MOF-399) and pto topologies (Cu(3)(4,4',4''-(benzene-1,3,5-triyl-tribenzoate)(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.
本文回顾了同构（相同拓扑）系列金属有机骨架（MOF）的概念和出现。我们描述了三种新的 MOF 的制备、表征和晶体结构，它们是具有已知材料拓扑结构的同构扩展，拓扑结构分别为 tbo（Cu(3)(4,4',4''-(苯-1,3,5-三基-三(苯-4,1-二基))三苯甲酸酯)(2), MOF-399）和 pto（Cu(3)(4,4',4''-(苯-1,3,5-三基三苯甲酸酯)(2), MOF-143；Cu(3)(4,4',4''-(三嗪-2,4,6-三基-三(苯-4,1-二基))三苯甲酸酯)(2), MOF-388）。这些材料中的一种（MOF-399）的晶胞体积比与之同构的第一个报道的材料大 17 倍，并且具有迄今为止报道的 MOFs 中最高的孔隙率（94%）和最低的密度（0.126 g cm(-3)）。
