Abstract
Na8Mg3Si9O24(OH)(2) and Na8Mg3Si9O24(OH,Cl)(2) have been prepared by s olid state reaction at ca. 700 degrees C in air. These new materials h ave the sodalite structure type with I-centred cubic unit cells of dim ensions a = 9.059(2) and 8.989(1) Angstrom, respectively. The magnesiu m and silicon atoms in the sodalite framework are disordered with the interstitial sodium ions being partially exchangeable at 85 degrees C. These materials represent only the second type of magnesiosilicate fr amework structure reported.
