Dy2Ni2Sn crystallizes in the tetragonal P4/mbm space group. Dy(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 Dy(1), one Ni(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Dy(1) and four equivalent Ni(1) atoms to form a mixture of corner and face-sharing SnDy8Ni4 cuboctahedra.
Dy2Ni2Sn crystallizes in the tetragonal P4/mbm space group. Dy(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. There are two shorter (2.80 Å) and four longer (2.85 Å) Dy(1)-Ni(1) bond lengths. All Dy(1)-Sn(1) bond lengths are 3.25 Å. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), one Ni(1), and two equivalent Sn(1) atoms. The Ni(1)-Ni(1) bond length is 2.46 Å. Both Ni(1)-Sn(1) bond lengths are 2.93 Å. Sn(1) is bonded to eight equivalent Dy(1) and four equivalent Ni(1) atoms to form a mixture of corner and face-sharing SnDy8Ni4 cuboctahedra.
