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) (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.
