Abstract: A silica polymorph, silica-sodalite was synthesized from a nonaqueous system NaOH-SiO2-C2H4(OH)2 and its chemical compositionwas determined to be Si12O24,2C2H4(OH)2 by the X-fluorescence,thermogravimetric and organic elemental analyses. The single crystal X-ray diffraction structure determination of the silica-sodaliteshowed that the silica-sodalite is cubic, spacing group I23 and unitcell parameter a= 8.8354Å. The IF and solid state high resolution 29Si and 13C NMR spectra of the silica-sodalite were measured and discussed.

Key words: nonaqueous system, silica-sodalite, synthesis structure.
