Materials Data on Sc2Ni2Sn by Materials Project
Sc2Ni2Sn crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Sc is bonded in a 6-coordinate geometry to six equivalent Ni and four equivalent Sn atoms. There are two shorter (2.68 Å) and four longer (2.70 Å) Sc–Ni bond lengths. All Sc–Sn bond lengths are 3.14 Å. Ni is bonded in a 6-coordinate geometry to six equivalent Sc, one Ni, and two equivalent Sn atoms. The Ni–Ni bond length is 2.50 Å. Both Ni–Sn bond lengths are 2.83 Å. Sn is bonded to eight equivalent Sc and four equivalent Ni atoms to form a mixture of distorted corner and face-sharing SnSc8Ni4 cuboctahedra.
