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.
