Abstract: The present invention relates to a zeolitic material having the IWR type framework structure, wherein the zeolitic material comprises YO2 and X2O3 in its framework structure, wherein Y is a tetravalent element and X is a trivalent element, and wherein the framework structure of the zeolitic material comprises less than 5 weight-% weight-% of Ge calculated as GeO2 and based on 100 weight-% weight-% of YO2 contained in the framework structure, and less than 5 weight-% weight-% of B calculated as B2O3 and based on 100 weight-% weight-% of X2O3 contained in the framework structure. Further, the present invention relates to a process for preparing a zeo-litic material having the IWR type framework structure, wherein the zeolitic material comprises YO2 and X2O3 in its framework structure, wherein Y is a tetravalent element and X is a trivalent element.
