Abstract / Description:AgAsO3 was prepared, for the first time, through solid state reaction
of Ag2O and As2O3, or As, respectively, while applying an elevated
oxygen pressure (T = 500 degreesC, p(O-2) = 2 kbar, 1-2 days). The
crystal structure (Pca2(1); a = 1948.8(3), b = 660.0(1), c = 1266.1(3)
pm; Z = 24; 4741 independent reflexions; R-1 = 0.044) contains a novel
polyanion, (1)(infinity)[(AsO6/2)(AsO2/1O2/2)(2)], with arsenic in an
octahedral and tetrahedral coordination, at the same time. It thus
features structural units similar to those in binary As2O5.
