Sn3Sb is beta Sn-derived structured and crystallizes in the orthorhombic C222 space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form distorted corner-sharing SnSn6 pentagonal pyramids. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sb(1) atoms. Sb(1) is bonded in a 6-coordinate geometry to four equivalent Sn(2) and two equivalent Sb(1) atoms.

In the first Sn site, Sn(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form distorted corner-sharing SnSn6 pentagonal pyramids. Both Sn(1)-Sn(1) bond lengths are 3.17 Å. All Sn(1)-Sn(2) bond lengths are 3.06 Å. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sb(1) atoms. Both Sn(2)-Sn(2) bond lengths are 3.17 Å. Both Sn(2)-Sb(1) bond lengths are 3.08 Å. Sb(1) is bonded in a 6-coordinate geometry to four equivalent Sn(2) and two equivalent Sb(1) atoms. Both Sb(1)-Sb(1) bond lengths are 3.17 Å.
