Two groups of compounds with large porous superframeworks based on anion-centered [OT4] tetrahedral and the features of their extraframework subsystems

Two groups of compounds with the tetrahedral differently charged {(\textrmTO4)6[\textrmT4s\textrmO]2}n+ superframework and different extraframework compensatory subsystems are presented. The first group is characterized bya constant composition of the framework with the same topology and extraframework water-cation associates of the zeolite type with different compositions and configurations. Due to a low charge of the framework, the space of its large voids, along with monovalent cations, is forcedly occupied by neutral H₂O molecules. In the second group, the composition and topology of a highly charged framework are variable, with a stable three-dimensional network of large extraframework cations. The effect of the framework charge on the features of its configuration is considered.
