Abstract

By application of a combinatorial approach, a new open‐framework zinc phosphate [C~6~H~16~N~2~]·[Zn~2~(HPO~4~)~3~] (denoted as phase D) has been obtained in the Zn(OAc)~2~·2H~2~O/H~3~PO~4~/N,N′‐dimethylpiperazine/ethylene glycol solvothermal reaction system at 180 °C. The factors influencing formation of the reaction products, such as crystallization temperature, solvent, as well as gel compositions, have been systematically studied. Phase D was characterized by X‐ray powder diffraction, ICP, and TG analyses, and its structure was determined by single‐crystal X‐ray diffraction analysis. It crystallizes in the monoclinic space group __P__2~1~/n (no.14), with a = 8.6931(3) Å, b = 14.4394(5) Å, c = 12.6492(3) Å, β = 96.418(2)°, and Z = 4. It is composed of ZnO~4~, PO~3~(OH) and PO~2~(OH)(=O) tetrahedral units linked by Zn−O−P bonds, forming an open‐framework with intersecting eight‐membered ring channels along the [100], [010], and [101] directions.
