摘要：

The synthesis and structural study of three new A(II)((Sb0.5Fe0.5III)-Fe-V)(PO4)(2) (A=Ba, Sr, Pb) phosphates belonging to the A-Sb-Fe-P-O system were reported here for the first time. Structures of [Ba], [Sr] and [Pb] compounds, obtained by solid state reaction in air atmosphere, were determined at room temperature from X-ray powder diffraction using the Rietveld method. Ba-II(Sb(V)0.5Fe(III)0.5)(PO4)(2) features the yavapaiite-type structure, with space group C2/m, Z = 2 and a = 8.1568(4) angstrom; b = 5.1996(3) angstrom c = 7.8290(4) angstrom; beta = 94.53(1)degrees. A(II)((Sb0.5Fe0.5III)-Fe-V)(PO4)(2) (A=Sr, Pb) compounds have a distorted yavapaiite structure with space group C2/c, Z = 4 and a = 16.5215(2) angstrom; b = 5.1891(1) angstrom a = 8.0489(1) angstrom; beta = 115.70(1)degrees for [Sr]; a = 16.6925(2) angstrom; b = 5.1832(1) angstrom c = 8.1215(1) angstrom; beta = 115.03(1)degrees for [Pb]. Raman and Infrared spectroscopic study was used to obtain further structural information about the nature of bonding in selected compositions. (C) 2016 Elsevier Masson SAS. All rights reserved.
