Ni3Sn2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 11-coordinate geometry to six equivalent Ni(2), two equivalent Sn(1), and three equivalent Sn(2) atoms. In the second Ni site, Ni(2) is bonded in a 11-coordinate geometry to two equivalent Ni(2), three equivalent Ni(1), three equivalent Sn(1), and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Ni(1), six equivalent Ni(2), and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a distorted q6 geometry to three equivalent Ni(1) and six equivalent Ni(2) atoms.

In the first Ni site, Ni(1) is bonded in a 11-coordinate geometry to six equivalent Ni(2), two equivalent Sn(1), and three equivalent Sn(2) atoms. There are a spread of Ni(1)-Ni(2) bond distances ranging from 2.63-2.68 Å. There is one shorter (2.48 Å) and one longer (2.49 Å) Ni(1)-Sn(1) bond length. There is one shorter (2.56 Å) and two longer (2.58 Å) Ni(1)-Sn(2) bond lengths. In the second Ni site, Ni(2) is bonded in a 11-coordinate geometry to two equivalent Ni(2), three equivalent Ni(1), three equivalent Sn(1), and three equivalent Sn(2) atoms. There is one shorter (2.54 Å) and one longer (2.62 Å) Ni(2)-Ni(2) bond length. There are two shorter (2.64 Å) and one longer (2.89 Å) Ni(2)-Sn(1) bond length. There are a spread of Ni(2)-Sn(2) bond distances ranging from 2.61-2.70 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Ni(1), six equivalent Ni(2), and two equivalent Sn(1) atoms. Both Sn(1)-Sn(1) bond lengths are 3.13 Å. In the second Sn site, Sn(2) is bonded in a distorted q6 geometry to three equivalent Ni(1) and six equivalent Ni(2) atoms.
