Title: Materials Data on Dy4Ga16Co3 by Materials Project

Abstract

Dy4Co3Ga16 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Dy is bonded to twelve Ga atoms to form DyGa12 cuboctahedra that share corners with eight equivalent DyGa12 cuboctahedra, edges with two equivalent GaDy4Ga8 cuboctahedra, faces with two equivalent GaDy4Ga8 cuboctahedra, faces with five equivalent DyGa12 cuboctahedra, and faces with two equivalent CoGa6 octahedra. There are a spread of Dy–Ga bond distances ranging from 3.00–3.05 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to eight Ga atoms. All Co–Ga bond lengths are 2.48 Å. In the second Co site, Co is bonded to six Ga atoms to form CoGa6 octahedra that share corners with eight equivalent GaDy4Ga8 cuboctahedra and faces with eight equivalent DyGa12 cuboctahedra. There are four shorter (2.39 Å) and two longer (2.43 Å) Co–Ga bond lengths. There are seven inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy, two equivalent Co, and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.56–3.02 Å. In the second Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy,more » two equivalent Co, and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.56–3.02 Å. In the third Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy, two equivalent Co, and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.56–2.97 Å. In the fourth Ga site, Ga is bonded in a 4-coordinate geometry to two equivalent Dy, two equivalent Co, and seven Ga atoms. Both Ga–Dy bond lengths are 3.00 Å. There are a spread of Ga–Ga bond distances ranging from 2.82–3.02 Å. In the fifth Ga site, Ga is bonded in a 1-coordinate geometry to four equivalent Dy, one Co, and four Ga atoms. There are two shorter (2.65 Å) and two longer (2.89 Å) Ga–Ga bond lengths. In the sixth Ga site, Ga is bonded to four equivalent Dy and eight Ga atoms to form distorted GaDy4Ga8 cuboctahedra that share corners with four equivalent GaDy4Ga8 cuboctahedra, corners with four equivalent CoGa6 octahedra, edges with four equivalent DyGa12 cuboctahedra, a faceface with one GaDy4Ga8 cuboctahedra, and faces with four equivalent DyGa12 cuboctahedra. The corner-sharing octahedral tilt angles are 50°. In the seventh Ga site, Ga is bonded in a 5-coordinate geometry to four equivalent Dy, one Co, and four Ga atoms.« less
