Materials Data on Rb3Mg by Materials Project

Abstract

Rb3Mg crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are three inequivalent Rb sites. In the first Rb site, Rb is bonded in a 2-coordinate geometry to eight Rb and two equivalent Mg atoms. There are a spread of Rb–Rb bond distances ranging from 4.33–4.89 Å. Both Rb–Mg bond lengths are 4.32 Å. In the second Rb site, Rb is bonded in a 2-coordinate geometry to eight Rb and two equivalent Mg atoms. Both Rb–Rb bond lengths are 4.52 Å. Both Rb–Mg bond lengths are 4.32 Å. In the third Rb site, Rb is bonded in a 2-coordinate geometry to eight Rb and two equivalent Mg atoms. Both Rb–Mg bond lengths are 4.32 Å. Mg is bonded in a 6-coordinate geometry to six Rb atoms.
