On the Isomorphism of Sodium at the M (2) Site in Eudialyte-Group Minerals: The Crystal Structure of Mn-Deficient Manganoeudialyte and the Problem of the Existence of the M (2) Na-Dominant Analogue of Eudialyte
Sodium plays an important role in the crystal structures of eudialyte-group minerals given that it can occupy different crystallographic sites. Predominantly, it distributes between the N (1–5) sites situated in the large cavities of the heteropolyhedral framework. Rarely, Na occupies split sites of...
