It crystallizes within the orthorhombic space group Fdd2, with the following cell constants: a=18.2930(2)Å; b=18.6430(5)Å; c=6.5860(5)Å; V=2246.07(18)Å3. The three-dimensional framework of this hydrated aluminosilicate zeolite is made up by chains of corner-sharing SiO4 and AlO4 tetrahedra down c; the chains are held together by sharing the external vertices of tetrahedra; water molecules and Na+ extra-framework cations fill up the resulting cavities, the latter forming irregular NaO6 octahedra. Hydrogen bonds complete the array.
