Three new micro-porous silicogermanates, (NH4)F[(Ge3.14Si6.86)O20] (SU-9), (NH4F[(Ge6.78Si3.22)O20] (SU-10) and [(Ge2.40Si9.60)O24] (SU-11) were synthesized under hydrothermal conditions with the presence of structure directing agents and the structures were solved by single crystal X-ray diffraction. SU-9 and SU-10 are built up by the double T4-rings (D4Rs) and they have the zeolite structure types of AST and ASV, respectively. SU-11 is built up by the T12-units and has the zeolite structure type of MFI. In three compounds, both silicon and germanium atoms are tetrahedrally coordinated with oxygen atoms and share the same tetrahedral sites.
