摘要：

The crystal structure of zeolite N (EDI type framework) has been refined using high-resolution synchrotron powder diffraction data. The structure is pseudotetragonal. The orthorhombic distortion is observable as a slight line broadening, a=990.41(2), b=988.60(2), c=1309.00(2) pm, space group 1222, No. 23, Z=1, for the composition K12Al10Si10O40Cl2 . 8H(2)O. The AlO4 and SiO4 tetrahedra form an ordered arrangement similar to that in edingtonite. The potassium and chlorine atoms form deformed ClK6 octahedra positioned in the channels running along [001].
