    Das erste Erdalkalimetall-Argentato-Mercurat(II): BaAg2Hg2O4 (1991)
    Springer
    Monatshefte für Chemie 122 (1991), S. 915-920 
    Details
    ISSN: 1434-4475
    Keywords: Barium ; Silver ; Mercury ; Oxide ; High-pressure synthesis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary BaAg2Hg2O4 was prepared by an oxygen high-pressure technique. Single crystal X-ray investigations led to tetragonal symmetry, space group D 4h 3 − P4/nbm;a=6.793;c=7.086 Å;Z=2. Hg2+ and Ag+ show dumb-bell like coordination by oxygen whereas Ba2+ ions are surrounded by 8 O2− forming distorted cubes. The BaO8-polyhedra distortions are discussed in respect to the incorporation of Hg2+ ions into the BaAg2O 4 2− network.

    Topics: Chemistry and Pharmacology
    Notes: Summary Ba0.75Sr0.25HgO2 was prepared for the first time by an oxygen high-pressure technique. Single cystal X-ray investigations lead to hexagonal symmetry, space group D 6 6 -P6322;a=6.897;c=11.986 Å;Z=6. Hg2+-ions show a dumbbell-like coordination by two O2−-ions. The alkaline earth ions Ba2+ and Sr2+ are surrounded by deformed trigonal O2−-prisms. Only one of the two Ba2+ point positions of the BaHgO2-type can be substituted by Sr2+. Polyhedra size and deformation are discussed in respect to the exchange of Ba2+ by Sr2+.

    Description / Table of Contents: On (Ba0,5Sr0,5)Cu2V2O8 and Ba(CuMg)V2O8Single Crystals of (A): (Ba0.5Sr0.5)Cu2V2O8 and (B) Ba(CuMg)V2O8 were prepared by solid state reactions below the melting points of the starting mixtures. Both compounds were examined by X-ray technique. They crystallize in the space groups (A): 142d [No. 122]; a = 12.65; c = 8.18 Å; Z = 8; and (B): 141/acd [No. 142]; a = 12.50; c = 8.33 Å; Z = 8. In (A) are Ba2+ plus Sr2+ and in (B) are Cu2+ plus Mg2+ in statistical distribution. The square pyramidal Cu2+ coordination in (A) is changed to an octahedron in (B), by replacing Cu2+ by Mg2+.
