Li2Sn5 crystallizes in the tetragonal P4/mbm space group. Li(1) is bonded in a 10-coordinate geometry to two equivalent Sn(2) and eight equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(2) is bonded in a 4-coordinate geometry to four equivalent Li(1) and four equivalent Sn(1) atoms. In the second Sn site, Sn(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), one Sn(2), and five equivalent Sn(1) atoms.
Li2Sn5 crystallizes in the tetragonal P4/mbm space group. Li(1) is bonded in a 10-coordinate geometry to two equivalent Sn(2) and eight equivalent Sn(1) atoms. Both Li(1)-Sn(2) bond lengths are 3.00 Å. There are four shorter (3.04 Å) and four longer (3.23 Å) Li(1)-Sn(1) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(2) is bonded in a 4-coordinate geometry to four equivalent Li(1) and four equivalent Sn(1) atoms. All Sn(2)-Sn(1) bond lengths are 3.11 Å. In the second Sn site, Sn(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), one Sn(2), and five equivalent Sn(1) atoms. There are a spread of Sn(1)-Sn(1) bond distances ranging from 3.11-3.23 Å.
