Crystalline Zinc Diphosphonate Metal−Organic Framework with Three-Dimensional Microporosity

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)](DMF)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.
