    Use of molecular symmetry in two-electron integral transformation An MP2 program compatible with HONDO 5 (1984)

    Notes: A computer program is described which evaluates the second-order Møller-Plesset energy using the integral list formed by HONDO 5. In this program use may be made of full molecular symmetry for most common point groups, even if they contain two-dimensional representations. The algorithm for the integral transformation may also be applied to other methods beyond Hartree-Fock. Some numerical results and timings are presented.

    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.
