Title: Low-temperature flux syntheses and characterizations of two 1-D anhydrous borophosphates: Na{sub 3}B{sub 6}PO{sub 13} and Na{sub 3}BP{sub 2}O{sub 8}

Abstract

Two new anhydrous sodium borophosphates with one-dimensional structure, Na{sub 3}B{sub 6}PO{sub 13}(1) and Na{sub 3}BP{sub 2}O{sub 8}(2), were synthesized by low-temperature molten salts techniques using boric acid and sodium dihydrogen phosphate as flux, respectively. The crystal structures were solved by means of single-crystal X-ray diffraction (1, orthorhombic, Pnma (no. 62), a=9.3727(4)A, b=16.2307(7)A, c=6.7232(3)A, Z=4; 2 , monoclinic, C2/c (no. 15), a=12.567(4)A, b=10.290(3)A, c=10.210(3)A, {beta}=92.492(5){sup o}, Z=8). Compound 1 is characterized by an infinite chain of {sub {approx}}{sup 1}{l_brace}[B{sub 6}PO{sub 13}]{r_brace}{sup 3-} containing eight-membered rings in which all vertexes of borate groups contribute to interconnection. Compound 2 reveals an infinite straight chain {sub {approx}}{sup 1}{l_brace}[BP{sub 2}O{sub 8}]{r_brace}{sup 3-} built of vertex-sharing four-membered rings, and chains in neighboring layers arranged along different orientations. The relations between structures and the synthetic conditions with only traced water are discussed.
