Materials Data on DyGa3Ru by Materials Project
DyRuGa3 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to four equivalent Ru and ten Ga atoms. All Dy–Ru bond lengths are 3.22 Å. There are eight shorter (2.96 Å) and two longer (3.22 Å) Dy–Ga bond lengths. Ru is bonded to four equivalent Dy and eight equivalent Ga atoms to form distorted RuDy4Ga8 cuboctahedra that share corners with four equivalent RuDy4Ga8 cuboctahedra, edges with four equivalent GaDy6 octahedra, and faces with eight equivalent RuDy4Ga8 cuboctahedra. All Ru–Ga bond lengths are 2.67 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded to six equivalent Dy atoms to form GaDy6 octahedra that share corners with six equivalent GaDy6 octahedra and edges with twelve equivalent RuDy4Ga8 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. In the second Ga site, Ga is bonded in a 9-coordinate geometry to three equivalent Dy, three equivalent Ru, and three equivalent Ga atoms. All Ga–Ga bond lengths are 2.71 Å.
