o CMS2021 does not state a cell composition, but Figure shows dangling, unsaturated oxygen atoms and no fluorine atoms, rendering it plausible to assume that a model with sum formula Ga96P96O396 was used, as in SN2020. The same reasoning can be applied for the case of JC2024, notably on the basis of Figure . o Although the sum formula is not given in JML2022, a density of 1.129 g cm -3 is stated in Table . This is exactly the density of the purely siliceous model of the -CLO framework that is included in the IZADB. This purely hypothetical all-silica -CLO model has, again, dangling oxygen atoms and is therefore not neutral. As all T sites are occupied by the same element, silicon, the structure can be described in a smaller unit cell having composition Si192O396 (charge: -24 e).
