Figure 4
Tranformation of the ReO₃-type phase to, respectively, α- and γ-ZrF₄ structures through anionic bridging. (a) The basic bridging mechanism for anion insertion. (b) Ordered anionic bridging by F6 corners creating a 3².4.3.4 (001) cationic plane net in α-ZrF₄. (c) F1–F1 edges creating a [3².4³][3.4³] ( $[\overline{1}]$ 10) [identical to the homologous (110)] cationic plane net in γ-ZrF₄.
