CRYSTAL CHEMISTRY OF NOVEL “ANTIZEOLITE” STRUCTURES
Sergey V. Rashchenko, Tatyana B. Bekker
Abstract
Abstract The “antizeolite” concept, which was originally proposed for mayenite-type structures, can also be successfully applied to a number of compounds containing large cations and characterized by a conservative cationic “framework” with cavities, some of which can contain disordered and very diverse anionic clusters, similarly to the zeolite anionic frameworks whose large cavities contain variable cationic ensembles. This approach and its use to control the functional properties of corresponding materials are considered on the example of recently described novel “antizeolite” structural types such as barium orthoborate Ba3(BO3)2 and burbankite Na2Ca4(CO3)5.
