Zr4Sn3 crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 5-coordinate geometry to five equivalent Sn(1) atoms. In the second Zr site, Zr(2) is bonded in a 9-coordinate geometry to nine equivalent Sn(1) atoms. Sn(1) is bonded in a 8-coordinate geometry to three equivalent Zr(2) and five equivalent Zr(1) atoms.
Zr4Sn3 crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 5-coordinate geometry to five equivalent Sn(1) atoms. There are a spread of Zr(1)-Sn(1) bond distances ranging from 2.92-3.17 Å. In the second Zr site, Zr(2) is bonded in a 9-coordinate geometry to nine equivalent Sn(1) atoms. There are three shorter (3.05 Å) and six longer (3.33 Å) Zr(2)-Sn(1) bond lengths. Sn(1) is bonded in a 8-coordinate geometry to three equivalent Zr(2) and five equivalent Zr(1) atoms.
