Sm Sm Sm B
Sm3B crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sm3B cluster. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a single-bond geometry to one Sm(2) and one B(1) atom. The Sm(1)-Sm(2) bond length is 1.19 Å. The Sm(1)-B(1) bond length is 0.38 Å. In the second Sm site, Sm(2) is bonded in a 2-coordinate geometry to one Sm(1) and one B(1) atom. The Sm(2)-B(1) bond length is 1.40 Å. In the third Sm site, Sm(3) is bonded in a single-bond geometry to one B(1) atom. The Sm(3)-B(1) bond length is 2.20 Å. B(1) is bonded in a single-bond geometry to one Sm(1), one Sm(2), and one Sm(3) atom.
