Materials Data on RbMg3 by Materials Project
RbMg3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Rb is bonded in a 6-coordinate geometry to twelve equivalent Mg atoms. There are six shorter (4.01 Å) and six longer (4.29 Å) Rb–Mg bond lengths. Mg is bonded in a 10-coordinate geometry to four equivalent Rb and six equivalent Mg atoms. There are four shorter (3.13 Å) and two longer (3.15 Å) Mg–Mg bond lengths.
