Sn2Tb is Zirconium Disilicide structured and crystallizes in the monoclinic P2_1/m space group. Tb(1) is bonded in a 10-coordinate geometry to four equivalent Sn(2) and six equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to six equivalent Tb(1) and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Tb(1) and four equivalent Sn(2) atoms.
Sn2Tb is Zirconium Disilicide structured and crystallizes in the monoclinic P2_1/m space group. Tb(1) is bonded in a 10-coordinate geometry to four equivalent Sn(2) and six equivalent Sn(1) atoms. There are a spread of Tb(1)-Sn(2) bond distances ranging from 3.29-3.32 Å. There are a spread of Tb(1)-Sn(1) bond distances ranging from 3.16-3.47 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to six equivalent Tb(1) and two equivalent Sn(1) atoms. Both Sn(1)-Sn(1) bond lengths are 2.95 Å. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Tb(1) and four equivalent Sn(2) atoms. There are two shorter (3.08 Å) and two longer (3.09 Å) Sn(2)-Sn(2) bond lengths.
