    Description / Table of Contents: Ba(VO)As2O7 - a Vanadyl-Diarsenate with Layered StructureDark green single crystals of Ba(VO)As2O7 have been prepared by solid state reactions in closed quartz tubes. X-ray investigations led to monoclinic symmetry, space group C2h5 P21/a, a = 6.843(2), b = 14.636(4), c = 7.460(2) Å, β = 116.02(2)°, Z = 4. Ba(VO)As2O7 is nonisotypic to BaV3O8 (= Ba(VO)V2O7). The structure is characterized by ∞2[(VO)As2O7] layers parallel to (110), sandwiching Ba2+ ions. As5+ shows tetrahedral and V4+ square pyramidal coordination with one short V—O bond typical for vanadyl groups.
    Notes: Dunkelgrüne Einkristalle von Ba(VO)As2O7 wurden durch Festkörperreaktionen in geschlossenen Quarzampullen dargestellt. Röntgenographische Untersuchungen führten zu monokliner Symmetrie, Raumgruppe C2h5 P21/a, mit a = 6,843(2), b = 14,636(4), c = 7,460(2) Å, β = 116,02(2)°, Z = 4. Es besteht keine Isotypie zu BaV3O8 (= Ba(VO)V2O7). Die Kristallstruktur zeichnet sich durch ∞2[(VO)As2O7]-Schichten parallel zu (110) aus, die durch Ba2+-Ionen verknüpft werden. As5+ zeigt tetraedrische und V4+ die für Vanadylgruppen typische quadratisch pyramidale Koordination mit einem kurzen V—O-Abstand.
