A new quaternary vanadogermanate compound (H3deta)4Ge8V14S8O42 · H2O was synthesized under hydrothermal conditions and characterized by means of IR spectrum, TG, single X-ray and PXRD diffraction. The X-ray crystallography indicated the crystal crystallized in a tetragonal lattice, P-4m2 space group, a =b =0.9933(6) nm, c=2.3661(15) nm, a=β = γ = 90°, V = 2.335(2) nm-3 , Z = 8, R1 =0.0803, wR2 =0.2288. The structure of the compound showed a 2D layer skeleton parallel to the (001) plane, which was constructed by the interconnection of [Ge8V14SgO42]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.%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]12-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.
