【Abstract】 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,α=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 [Ge8V14S8O42]12-clusters through sharing common corners,the diethylenetriamine(deta) molecules with positive charges were filled into the space between skeletons to balance the negative charges of the structure.更多还原
