SrBi5 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a distorted bent 150 degrees geometry to one Bi(1), one Bi(2), one Bi(4), and one Bi(5) atom. The Sr(1)-Bi(1) bond length is 1.89 Å. The Sr(1)-Bi(2) bond length is 4.09 Å. The Sr(1)-Bi(4) bond length is 2.18 Å. The Sr(1)-Bi(5) bond length is 3.06 Å. There are five inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Sr(1) and one Bi(2) atom. The Bi(1)-Bi(2) bond length is 2.66 Å. In the second Bi site, Bi(2) is bonded in a 5-coordinate geometry to one Sr(1), one Bi(1), one Bi(3), and two equivalent Bi(2) atoms. The Bi(2)-Bi(3) bond length is 2.45 Å. Both Bi(2)-Bi(2) bond lengths are 3.58 Å. In the third Bi site, Bi(3) is bonded in a distorted bent 150 degrees geometry to one Bi(2) and one Bi(4) atom. The Bi(3)-Bi(4) bond length is 1.89 Å. In the fourth Bi site, Bi(4) is bonded in a distorted single-bond geometry to one Sr(1), one Bi(3), and one Bi(5) atom. The Bi(4)-Bi(5) bond length is 2.21 Å. In the fifth Bi site, Bi(5) is bonded in a 2-coordinate geometry to one Sr(1) and one Bi(4) atom.
