    Description / Table of Contents: HgPb2O2Cl2, a “Perforated” Lead(II) OxideSingle crystals of HgPb2O2Cl2 were grown in a HgCl2 flux by reaction of PbO with HgCl2. Crystal structure analysis by single crystal X-ray methods were carried out. HgPb2O2Cl2 crystallizes monoclinic with a = 11.788(2) Å, b = 3.910(1) Å, c = 7.749(2) Å, β = 122.64(3)°, space group C2/m (No. 12) and Z = 2. HgPb2O2Cl2 is the first member of a new structure type, closely related to the structure of PbO.
    Notes: Einkristalle von HgPb2O2Cl2 wurden durch Umsetzung von PbO und HgCl2 in HgCl2-Schmelzen gezüchtet. An ihnen wurde der Aufbau mittels Einkristallröntgenstrukturanalyse bestimmt. HgPb2O2Cl2 kristallisiert monoklin mit a = 11,788(2) Å, b = 3,910(1) Å, c = 7,749(2) Å, β = 122,64(3)°, Raumgruppe C2/m (Nr. 12) und Z = 2. HgPb2O2Cl2 ist der erste Vertreter eines neuen Strukturtyps, der kristallchemisch von der Struktur von PbO ableitbar ist.

    Description / Table of Contents: Ag2Pb8O7Cl4, a New Member of Lead(II) Oxyhalides with SilverAg2Pb8O7Cl4 is one among other products of the thermal decomposition of AgPb4O4Cl. Ag2Pb8O7Cl4 can be prepared directly by heating the binary components within a temperature range from 590°C to 620°C. The crystal structure was solved by single crystal X-ray methods. The compound crystallizes monoclinic with a = 12.411(4) Å, b = 17.99(3) Å, c = 14.785(4) Å, β = 147.01(2)°, Z = 4 with the space group P21/c. Ag2Pb8O7Cl4 shows remarkable structural features, e.g. silver tetrahedrally surrounded by chlorine.
    Notes: Bei der thermischen Zersetzung von AgPb4O4Cl entsteht u. a. Ag2Pb8O7Cl4. Diese Verbindung läßt sich aus den binären Komponenten im Temperaturbereich 590°C bis 620°C rein darstellen. Die Struktur konnte mit Hilfe der Einkristallröntgenstrukturanalyse ermittelt werden. Ag2Pb8O7Cl4 kristallisiert in der monoklinen Raumgruppe P21/c, Z = 4 mit den Gitterkonstanten a = 12,411(4) Å, b = 17,99(3) Å, c = 14,785(4) Å, β = 147,01(2)°. Ag2Pb8O7Cl4 zeigt bemerkenswerte Struktureigenschaften wie tetraedrisch von Chlor umgebenes Silber.
