摘要：

A new aluminium vanadium oxide hydroxide analog of the mineral augelite has been prepared by hydrothermal treatment of a 1:1:2.65 aqueous solution of V2O5, Al(NO3)(3) . 9H(2)O, and TMAOH at 200 degrees C for 5 days. X-Ray powder diffraction data show that this phase crystallizes with monoclinic symmetry with space group C2/m. The structure was solved by using direct methods and then full profile Rietveld refinement was carried out; it's cell parameters are: a = 13.5634(2) Angstrom, b = 8.2267(2) Angstrom, c = 5.31232(9) Angstrom and beta = 112.741(1)degrees in space group C2/m. The structure contains clusters of edge sharing AlO6 octahedra and AlO5 trigonal bipyramids. These clusters are joined together by VO4 tetrahedra.
