RbSb crystallizes in the triclinic P-1 space group. There are four inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 3-coordinate geometry to one Sb(1), one Sb(2), and one Sb(4) atom. The Rb(1)-Sb(1) bond length is 2.52 Å. The Rb(1)-Sb(2) bond length is 3.34 Å. The Rb(1)-Sb(4) bond length is 3.47 Å. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to one Rb(3), one Rb(4), two equivalent Rb(2), two equivalent Sb(1), and two equivalent Sb(3) atoms. The Rb(2)-Rb(3) bond length is 2.58 Å. The Rb(2)-Rb(4) bond length is 3.32 Å. There is one shorter (3.46 Å) and one longer (3.96 Å) Rb(2)-Rb(2) bond length. There is one shorter (3.64 Å) and one longer (4.08 Å) Rb(2)-Sb(1) bond length. There is one shorter (3.41 Å) and one longer (3.47 Å) Rb(2)-Sb(3) bond length. In the third Rb site, Rb(3) is bonded in a 2-coordinate geometry to one Rb(2), one Sb(1), and one Sb(3) atom. The Rb(3)-Sb(1) bond length is 1.98 Å. The Rb(3)-Sb(3) bond length is 2.74 Å. In the fourth Rb site, Rb(4) is bonded in a single-bond geometry to one Rb(2), one Sb(3), and one Sb(4) atom. The Rb(4)-Sb(3) bond length is 0.83 Å. The Rb(4)-Sb(4) bond length is 3.51 Å. There are four inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one Rb(3), and two equivalent Rb(2) atoms. In the second Sb site, Sb(2) is bonded in a water-like geometry to one Rb(1) and one Sb(4) atom. The Sb(2)-Sb(4) bond length is 0.92 Å. In the third Sb site, Sb(3) is bonded in a single-bond geometry to one Rb(3), one Rb(4), and two equivalent Rb(2) atoms. In the fourth Sb site, Sb(4) is bonded in a 3-coordinate geometry to one Rb(1), one Rb(4), and one Sb(2) atom.
