Rb3Sb is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a trigonal planar geometry to three equivalent Sb(1) atoms. In the second Rb site, Rb(2) is bonded in a 1-coordinate geometry to four equivalent Sb(1) atoms. Sb(1) is bonded in a 11-coordinate geometry to three equivalent Rb(1) and eight equivalent Rb(2) atoms.
Rb3Sb is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a trigonal planar geometry to three equivalent Sb(1) atoms. All Rb(1)-Sb(1) bond lengths are 3.68 Å. In the second Rb site, Rb(2) is bonded in a 1-coordinate geometry to four equivalent Sb(1) atoms. There is one shorter (3.74 Å) and three longer (4.14 Å) Rb(2)-Sb(1) bond lengths. Sb(1) is bonded in a 11-coordinate geometry to three equivalent Rb(1) and eight equivalent Rb(2) atoms.
