Sc2Au2Sn crystallizes in the tetragonal P4/mbm space group. Sc(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. Au(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1), one Au(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Sc(1) and four equivalent Au(1) atoms to form a mixture of distorted corner and face-sharing SnSc8Au4 cuboctahedra.
Sc2Au2Sn crystallizes in the tetragonal P4/mbm space group. Sc(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. There are two shorter (2.81 Å) and four longer (2.88 Å) Sc(1)-Au(1) bond lengths. All Sc(1)-Sn(1) bond lengths are 3.34 Å. Au(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1), one Au(1), and two equivalent Sn(1) atoms. The Au(1)-Au(1) bond length is 2.79 Å. Both Au(1)-Sn(1) bond lengths are 2.98 Å. Sn(1) is bonded to eight equivalent Sc(1) and four equivalent Au(1) atoms to form a mixture of distorted corner and face-sharing SnSc8Au4 cuboctahedra.
