Materials Data on Dy5Ni2Sb by Materials Project
Dy5Ni2Sb crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded to three equivalent Ni and two equivalent Sb atoms to form distorted DyNi3Sb2 trigonal bipyramids that share corners with four equivalent DyNi4Sb2 octahedra, corners with twelve equivalent DyNi3Sb2 trigonal bipyramids, edges with seven equivalent DyNi3Sb2 trigonal bipyramids, faces with two equivalent DyNi4Sb2 octahedra, and a faceface with one DyNi3Sb2 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 42–62°. There are two shorter (2.87 Å) and one longer (2.93 Å) Dy–Ni bond lengths. Both Dy–Sb bond lengths are 3.25 Å. In the second Dy site, Dy is bonded to four equivalent Ni and two equivalent Sb atoms to form distorted DyNi4Sb2 octahedra that share corners with six equivalent DyNi4Sb2 octahedra, corners with sixteen equivalent DyNi3Sb2 trigonal bipyramids, and faces with eight equivalent DyNi3Sb2 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 0–51°. All Dy–Ni bond lengths are 2.98 Å. Both Dy–Sb bond lengths are 3.35 Å. Ni is bonded in a 8-coordinate geometry to eight Dy atoms. Sb is bonded in a distorted q6 geometry to ten Dy atoms.
