中文摘要：
通过水热的方法合成了一例新的二维层状四元钒锗酸盐化合物（H3deta）4Ge8V14S8O42·H2O，并对其进行红外、热重以及X-射线单晶衍射和粉末衍射分析．晶体学测试结果表明：该化合物为四方晶系，P-4m2空间群，晶包参数a=b=0．9933（6）nm，c=2．3661（15）nm，α=β=γ=90°，V=2．335（2）nm^-3，Z=8，R1=0．0803，wR2=0．2288；该化合物由较大的[Ge8V14S8O42]舱。簇共顶点相连成（001）平面的二维（2D）层状骨架，骨架之间由带正电荷的二乙烯三胺（deta）分子填充．
英文摘要：
A new quaternary vanadogennanate compound （H3deta）4Ge8V14S8O42·H2O was synthesized under hydrothemml condi- tions and characterized by means of IR spectrum, TG, single X-ray and PXRD diffraction. The X-ray crystallography indicated the crystal crystallized in a telxagonal lattice, P-4m2 space group, afb=0.9933（6） nm, c =2.3661（15） ran, α =β=γ=90°, V= 2.335（2） nm-3, Z =8, Rt =0.0803, wR2 =0.2288. The structure of the compound showed a 2D layer skeleton paraUel to the （001） plane, which was constructed by the interconnection of [ Ge8V14S8O42 ]^12- clusters through sharing common comers, the di- ethylenetriamine （deta） molecules with positive charges were filled into the space between skeletons to balance the negative charges of the structure.
