Abstract:A layered zirconogermanate, (H2DETA)[ZrGe3O8F2](I), is hydro(solvo)thermally synthesized by using diethylenetriamine (DETA) as template，and structurally determined by X-ray single-crystal diffraction. (I) crystallizes in the monoclinic space group P21/c with data of unit cell: a=0.7644(2)nm, b=1.1235(2)nm, c=1.6860(3)nm, V=1.4479(5)nm3, μ(Mo Kα)=6.931mm-1, Z=4, R1=0.0402 for 3236 reflections with Fo> 2(Fo). The structure of (I) is formed by alternatively packing the inorganic layer of ZrGe3O8F2 and H2DETA templated molecules along (001) direction. It is worth pointing out that the odd bifurcated 7MR nets are surrounded by odd 3MR. The protonated and disordered H2DETA cations not only balance the superfluous charges of framework but also stabilize the structure of (I) by the hydrogen bond between -NH3 group and oxygen on the framework. Furthermore, IR and TG are utilized to characterize the structure and thermal stability, respectively.
