    Description / Table of Contents: A Contribution about a New Cobalt-rich Oxoarsenate/-vanadate: Co5AsVO10Single crystals of Co5AsVO10 were prepared by solid state reactions and investigated by X-ray structure determination. It crystallizes with monoclinic symmetry, space group C2h3-C2/m, a = 19.134, b = 6.095, c = 17.482 Å, β = 133.37°; Z = 8. The new structure type is characterized by layers of CoO6- and AsO6-octahedra with partly alternating occupation. The layers are connected by Co2+ within tetrahedral oxygen coordination and tetrahedra around statistically occupied point positions of V5+ /As5+.
    Notes: Einkristalle von Co5AsVO10 wurden durch Feststoffreaktionen erhalten und röntgenographisch untersucht. Diese Verbindung kristallisiert mit monokliner Symmetrie, Raumgruppe C2h3-C2/m; a = 19,134; b = 6,095; c = 17,482 Å; β = 133,37°; Z = 8. Der neue Strukturtyp ist durch CoO6- und AsO6-Oktaederschichten ausgezeichnet, die teilweise alternierend mit Co2+ und As5+ besetzt sind. Die Oktaederschichten werden durch Co2+ in tetraedrischer Koordination und statistisch mit V5+ und As5+ besetzte Punktlagen verknüpft.
