Crystal structure of Rb-elpasolite Rb2NaAlF6

  • 1. Moscow State University, Faculty of Geology (Russian Federation)

Description

Single crystals of Rb2NaAlF6, the Rb analogue of the mineral elpasolite, are obtained in the NaF-Rb2CO3-Al2O3-Rb3PO4-H2O system under hydrothermal conditions, and their structure is determined by X-ray diffraction (R = 0.0188): a = 8.3087(1) Å, space group Fm3bar m, Z = 4, and ρcalcd = 3.88 g/cm3. The hypothesis that Rb elpasolite exists in nature in late associations of pegmatites enriched in rubidium is proposed.
