Materials Data on DyNi3Sn2 by Materials Project
DyNi3Sn2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a hexagonal planar geometry to six equivalent Ni atoms. All Dy–Ni bond lengths are 3.01 Å. In the second Dy site, Dy is bonded in a 12-coordinate geometry to twelve Ni and six equivalent Sn atoms. There are six shorter (3.21 Å) and six longer (3.42 Å) Dy–Ni bond lengths. All Dy–Sn bond lengths are 3.22 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a 9-coordinate geometry to three Dy, two equivalent Ni, and four equivalent Sn atoms. Both Ni–Ni bond lengths are 2.62 Å. All Ni–Sn bond lengths are 2.58 Å. In the second Ni site, Ni is bonded to four equivalent Dy, four equivalent Ni, and four equivalent Sn atoms to form a mixture of face and corner-sharing NiDy4Ni4Sn4 cuboctahedra. All Ni–Sn bond lengths are 2.65 Å. Sn is bonded in a 12-coordinate geometry to two equivalent Dy and six Ni atoms.
