The haüyne that belong to the sodalite group have a modulated structure. In this study, we analyzed the crystal structure of haüyne having a modulated structure and reexamined the factors of the modulatied structure of haüyne. For the experiments, single crystal X-ray diffraction experiments and crystal structure analysis were performed using haüyne from EIfel, Germany. As a result of comparing other structural models, it is concluded that the splitting of the oxygen site of the framework structure is due to the distribution of Si/Al that constitutes the framework.
