...) with the ABC sequence. The maximum number of layers within a unit cell observed for the framework of the supergroup so far is 36, found in kircherite ( Cámara et al. , 2012 ). Considering a single layer of 6-membered rings as a CBU (or PerBU ), the cancrinite-sodalite supergroup can be described...
