Zn3Sn crystallizes in the triclinic P-1 space group. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 6-coordinate geometry to three equivalent Zn(2), three equivalent Zn(3), and two equivalent Sn(1) atoms. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to three equivalent Zn(1), three equivalent Zn(3), and three equivalent Sn(1) atoms. In the third Zn site, Zn(3) is bonded in a 9-coordinate geometry to three equivalent Zn(1), three equivalent Zn(2), and three equivalent Sn(1) atoms. Sn(1) is bonded in a 7-coordinate geometry to two equivalent Zn(1), three equivalent Zn(2), and three equivalent Zn(3) atoms.

In the first Zn site, Zn(1) is bonded in a 6-coordinate geometry to three equivalent Zn(2), three equivalent Zn(3), and two equivalent Sn(1) atoms. There are a spread of Zn(1)-Zn(2) bond distances ranging from 2.56-3.11 Å. There are a spread of Zn(1)-Zn(3) bond distances ranging from 2.65-3.04 Å. There is one shorter (2.80 Å) and one longer (2.99 Å) Zn(1)-Sn(1) bond length. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to three equivalent Zn(1), three equivalent Zn(3), and three equivalent Sn(1) atoms. There are a spread of Zn(2)-Zn(3) bond distances ranging from 2.60-2.99 Å. There are a spread of Zn(2)-Sn(1) bond distances ranging from 2.84-3.37 Å. In the third Zn site, Zn(3) is bonded in a 9-coordinate geometry to three equivalent Zn(1), three equivalent Zn(2), and three equivalent Sn(1) atoms. There is one shorter (2.80 Å) and two longer (2.93 Å) Zn(3)-Sn(1) bond lengths. Sn(1) is bonded in a 7-coordinate geometry to two equivalent Zn(1), three equivalent Zn(2), and three equivalent Zn(3) atoms.
