Description
A model of the atomic structure of a monoclinic, pseudorhombic fluorite - like phase of NaYb2F7 is proposed. Multiatomic clusters of Na8Yb6F68, forming layers with the cation composition of Na4Yb6, provide the basis for simulation. Combination of clusters from different layers in the proposed model is carried out in two ways: like in the structure of KHo2F7 and like in the hypothetical triclinic structure of NaR2F7. The approximate coordinates of atoms of the NaYb2F7 hypothetical structure, which can serve as a stratified model to specify the structural parameters according to the monoclinic data
