Sc2Ni2Sn crystallizes in the tetragonal P4/mbm space group. Sc(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1), one Ni(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Sc(1) and four equivalent Ni(1) atoms to form a mixture of face and corner-sharing SnSc8Ni4 cuboctahedra.
Sc2Ni2Sn crystallizes in the tetragonal P4/mbm space group. Sc(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. There are two shorter (2.67 Å) and four longer (2.70 Å) Sc(1)-Ni(1) bond lengths. All Sc(1)-Sn(1) bond lengths are 3.12 Å. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1), one Ni(1), and two equivalent Sn(1) atoms. The Ni(1)-Ni(1) bond length is 2.45 Å. Both Ni(1)-Sn(1) bond lengths are 2.80 Å. Sn(1) is bonded to eight equivalent Sc(1) and four equivalent Ni(1) atoms to form a mixture of face and corner-sharing SnSc8Ni4 cuboctahedra.
