【Abstract】 College of Chemistry and Material Science, Hebei Normal University, Shijiazhuang, Hebei Polyoxovanadates have received much attention because of their structural variety and extenstive applications in magnetism, catalysis and materials science [1-3] . Herein, one novel 2D layer compound based on {V15Ge6O48 } has been hydrothermal synthesiszed by in situ deamination coupling reaction (DCR) reaction, namely, {[Zn2(en)(dien)(trien)][Zn4(en)2(dien)2 (trien)3 ]}[V15Ge6O48 (H2O)]·3H2O(1), (en = ethylenediamine, dien =diethylenetriamine, trien = triethylenediamine), which was characterized by element analysis, IR spectrum, XPS, and single-crystal X-ray diffraction. The crystallographic studies reveal that the title compound crystallizes in orthorhombic system, Pbcn space group. X-ray crystal structure analyses reveal that compound 1 consist of a rare [V15Ge 6O48 (H2O)]12- anion and two types of ZnⅡ -complex fragments. The neighbouring [V15G6O48(H2O)]12-polyoxoanions are linked through ZnⅡ-complex fragments to give rise to a two-dimensional structure. Magnetic measurement indicates that compound 1 have antiferromagnetic interactions.更多还原
