Materials Data on Dy2Ni2Sn by Materials Project
Dy2Ni2Sn crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Dy is bonded in a 10-coordinate geometry to six equivalent Ni and four equivalent Sn atoms. There are two shorter (2.80 Å) and four longer (2.88 Å) Dy–Ni bond lengths. All Dy–Sn bond lengths are 3.27 Å. Ni is bonded in a 9-coordinate geometry to six equivalent Dy, one Ni, and two equivalent Sn atoms. The Ni–Ni bond length is 2.48 Å. Both Ni–Sn bond lengths are 2.90 Å. Sn is bonded to eight equivalent Dy and four equivalent Ni atoms to form a mixture of face and corner-sharing SnDy8Ni4 cuboctahedra.
