| Abstract: | Concerning Potassium Arsenites in the Three-Component System K2O? As2O3? H2O. Preparation and Crystal Structure of K3(HAs2O4) (As2O4) · 3/2 H2O The phase K3(HAs2O4)(As2O4) · 3/2 H2O has been identified in the system K2O? As2O3? H2O at 40°C and characterized by X-ray structural analysis. In the crystal lattice independent polymetaarsenite anions, HAs2O4?]n and As2O42?]n, adopt parallel zweier single chains. |
