Abstract
Brownish crystals of Rb-6(V2O3)(2)(VO)(2)(PO4)(4)(HP2-xVxO7) were prepared hydrothermally. The structure was solved from single crystal X-ray diffract ion data in the non centrosymmetric orthorhombic space group Pmn2(1), (No. 31)a=13.5505(2) Angstrom, b=7.1407(2) Angstrom, c=14.7040(2) Angstrom. (R-1 (Fo)=0.048, wR(2)(Fo(2))=0.111). The structure of Rb-6(V2O3)(2)(VO)(2)(PO4) (4)(HP2-xVxO7) is closely related to the previously reported M-3(V2O3)(VO)( PO4)(2)(HPO4) (M=K+, Tl+) with a disordered occupation of the tetrahedral v oids by VV and PY atoms.
