RbBi3 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded in a 11-coordinate geometry to three equivalent Bi(2) and eight equivalent Bi(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Bi(1) atom. In the second Bi site, Bi(2) is bonded in a trigonal planar geometry to three equivalent Rb(1) atoms.
RbBi3 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded in a 11-coordinate geometry to three equivalent Bi(2) and eight equivalent Bi(1) atoms. All Rb(1)-Bi(2) bond lengths are 3.36 Å. There are two shorter (3.58 Å) and six longer (3.71 Å) Rb(1)-Bi(1) bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Bi(1) atom. The Bi(1)-Bi(1) bond length is 3.16 Å. In the second Bi site, Bi(2) is bonded in a trigonal planar geometry to three equivalent Rb(1) atoms.
