    Description / Table of Contents: Summary The crystal structure of the new mineral warikahnite, Zn3[(H2O)2|(AsO4)2], was determined from diffractometer data and refined toR=0,038 for 3428 observed independent reflections. Warikahnit is triclinic, $$P\bar 1$$ , witha=6.710(1),b=8.989(2),c=14.533(2) Å, α=105.59(1), β=93.44(1), γ=108.68(1)°,Z=4. The crystal structure of warikahnite contains 6 different coordination polyhedra of zinc with the coordination numbers 6,5 and 4 and with 5 different combinations of ligand. The hydrogen bonds are discussed on the basis of charge balance and IR spectra.

    Description / Table of Contents: AgCo3H2(AsO4)3 and AgZn3H2(AsO4)3. Preparation and Crystal Structure. Another New Structure Type of an ArsenateAgCo3H2(AsO4)3 (1) and AgZn3H2(AsO4)3 (2) were prepared by heating of As2O5, AgNO3, CoSO4 · 7H2O, ZnSO4 · 7H2O, respectively, and water in a sealed tube at 300°C and investigated with X-rays. Both compounds are isotypic and crystallize in the monoclinic space group C2/c with 4 formula units per cell. The lattice parameters are (1): a = 1215.9(6), b = 1243.8(7), c = 678.2(3) pm, β = 113.16(3)° (2): a = 1216.9(2), b = 1249.5(3), c = 675.5(1) pm, β = 112.77(1)°. The structure contains chains of edge-shared CoO6 or ZnO6 octahedra, respectively, which are connected by AsO4 tetrahedra and silver oxygen ribbons with square planar coordinated silver forming a framework. Based on the charge balances derived from the geometrical data and the IR spectra the occurence of hydrogen bonds is discussed.
    Notes: AgCo3H2(AsO4)3 (1) und AgZn3H2(AsO4)3 (2) wurden durch Erhitzen eines Gemisches von As2O5, AgNO3, CoSO4 · 7H2O bzw. ZnSO4 · 7H2O und Wasser auf 300°C im Autoklaven dargestellt und röntgenographisch untersucht. Beide Verbindungen sind isotyp und kristallisieren in der monoklinen Raumgruppe C2/c mit 4 Formeleinheiten in der Elementarzelle. Die Gitterkonstanten sind: (1) a = 1215,9(6), b = 1243,8(7), c = 678,2(3) pm, β = 113,16(3)° (2) a = 1216,9(2), b = 1249,5(3), c = 675,5(1) pm,β = 112,77(1)°. Die Struktur enthält Ketten aus kantenverknüpften CoO6- bzw. ZnO6-Oktaedern, welche über AsO4-Tetraeder, sowie über Silber-Sauerstoff-Bänder mit quadratisch-planar koordiniertem Silber zu einem Gerüst verknüpft sind. Anhand der aus den geometrischen Daten berechneten Ladungsbilanzen und der IR-Spektren wird das Auftreten von Wasserstoffbrücken diskutiert.
