Abstract: | On the Oxoargentato(I)-aurat(III): Ba4AgAuO6 The hitherto unknown compound Ba4AgAuO6 was prepared by oxidizing Ba/Au/Ag alloy with BaO2/Ba(OH)2 mixture in closed Ag tubes. X-ray single crystal investigation led to orthorhombic symmetry space group D-Cmcm; a = 13.275; b = 5.782; c = 11.396 Å; Z = 4. Ba4AgAuO6 shows distorted pentagonal bipyramidal polyhedra around Ba2+ and square planar AuO4 polygones. Ag+ shows an unusual 2 + 2 coordination by O2?. |
