【Abstract】 A novel ethylenediamine templated open-framework vanadium phosphate （H₃NCH₂CH₂NH₃）₃ [（VO）₄（PO₄）₂（HPO₄）₄] has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Green needle-like compound crystallized in monoclinic space group C2/c with a=1.8505（9） nm, b=0.7089（4） nm, c=2.3304（10） nm, β=96.43（3）°, V=3.038（3） nm 3, Z=8, and R=0.067 for 1912 unique reflections. The structure consists of layers constructed of corner-sharing V（Ⅳ） octahedra, V（Ⅳ） trigonal bipyramids, （PO₄） 3- and （HPO₄） 2- tetrahedra, which are held together by hydrogen bonding interaction to form the tunnels paralleled to the c axis and the direction. Studies of crystal structure and crystal chemistry shows that this compound is a new VPO phase with an unique and topotactic two dimensional open framework structure.更多还原
