On Alkaline Earth Oxoargentates. I. Strontiumargentate SrAg6O4Single crystals of SrAg6O4 were prepared at 400-500°C and 4000 atm. O2-pressure. The X-ray investigation of the single crystals shows the orthorhombic space group D2h6-Pnna (a = 6.518, b = 12.416, c = 8.909 Å). Sr2+ is octahedral and most of the Ag+ surrounded by weakly angled dumbbells of oxygen. In addition of these configurations metallic regions were found.
Notes:
Einkristalle von SrAg6O4 wurden 400-500°C und 4000 atm O2-Druck dargestellt. Eine Röntgenuntersuchung dieser Einkristalle ergibt die Raumgruppe D2h6-Pnna (a = 6,518, b = 12,416, c = 8,909 Å). Sr2+ ist oktaedrisch und das meiste Ag+ durch schwach gewinkelte Hanteln von Sauerstoff umgeben. Daneben wurden metallische Bereiche gefunden.
