While typically structures from linear diphosphonate ligands form dense phases, we report that with the functionalized ligand 1,4-dihydroxy-2,5-benzenediphosphonate (DHBP) and Zn2+ a microporous network is formed. {Zn(DHBP)2} (1; DMF = dimethylformamide) possesses three-dimensional microporosity as shown by X-ray diffraction and confirmed by CO2 and N2 sorption studies. Compound 1 is composed of one-dimensional columns of tetrahedral Zn ions with homoleptic phosphonate coordination. This infinite building unit enables a robust and porous yet still crystalline material.
虽然通常线性二膦酸酯配体形成的结构会形成致密相，但我们报道，使用功能化配体1,4 - 二羟基 - 2,5 - 苯二膦酸酯（DHBP）和Zn²⁺会形成微孔网络。{Zn(DHBP)₂}（1；DMF = 二甲基甲酰胺）具有三维微孔性，X射线衍射表明了这一点，并且通过CO₂和N₂吸附研究得到了证实。化合物1由具有均配膦酸酯配位的四面体Zn离子的一维柱组成。这种无限的构建单元形成了一种坚固、多孔但仍为晶体的材料。
