A synthetic access to novel nitridozeolites has been opened by the formal exchange of oxygen for nitrogen in microporous oxozeolites. Ba 2 Nd 7 Si 11 N 23 is the first example of a network structure containing corner‐sharing SiN 4 tetrahedra with wide channels. In sharp contrast to conventional oxidic zeolites, this nitridozeolite is stable up to 1600 °C.
