Synthesis of a range of anion-containing gallium and germanium sodalites
Synthesis of a range of anion-containing gallium and germanium sodalites
The introduction of gallium and germanium into the sodalite framework has been achieved by hydrothermal and low temperature solution routes for a wide range of anions. This yields materials of general composition Na-8[ABO(4)](6).X-2, where A = Al and Ga, B = Si and Ge, and X includes Cl-, Br-, I-, (ClO3)(-), (BrO3)(-), (HCOO)(-), (MnO4)(-), (SCN)(-) and (SeCN)(-). Lithium and potassium exchanged derivatives of certain sodalites have also been prepared via reaction in nitrate melts. Intra-cage reactions performed on selected samples have permitted the preparation of such species as aluminogermanate sulphur and selenium ultramarines. Products have been characterised by powder X-ray and neutron diffraction, infra-red, Raman and magic angle spinning nuclear magnetic resonance spectroscopy, thermogravimetric analysis and flame photometry.

Abstract
The introduction of gallium and germanium into the sodalite framework has been achieved by hydrothermal and low temperature solution routes for a wide range of anions. This yields materials of general composition Na-8[ABO(4)](6).X-2, where A = Al and Ga, B = Si and Ge, and X includes Cl-, Br-, I-, (ClO3)(-), (BrO3)(-), (HCOO)(-), (MnO4)(-), (SCN)(-) and (SeCN)(-). Lithium and potassium exchanged derivatives of certain sodalites have also been prepared via reaction in nitrate melts. Intra-cage reactions performed on selected samples have permitted the preparation of such species as aluminogermanate sulphur and selenium ultramarines. Products have been characterised by powder X-ray and neutron diffraction, infra-red, Raman and magic angle spinning nuclear magnetic resonance spectroscopy, thermogravimetric analysis and flame photometry.
