Materials Data on CeGaNi4 by Materials Project
Abstract
CeNi4Ga crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ce is bonded in a 6-coordinate geometry to fifteen Ni and three equivalent Ga atoms. There are three shorter (2.94 Å) and twelve longer (3.20 Å) Ce–Ni bond lengths. All Ce–Ga bond lengths are 2.94 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded to three equivalent Ce, six equivalent Ni, and three equivalent Ga atoms to form distorted NiCe3Ga3Ni6 cuboctahedra that share corners with nine equivalent GaCe3Ni9 cuboctahedra, corners with twelve equivalent NiCe4Ga2Ni6 cuboctahedra, edges with six equivalent NiCe3Ga3Ni6 cuboctahedra, faces with three equivalent GaCe3Ni9 cuboctahedra, and faces with twenty NiCe3Ga3Ni6 cuboctahedra. All Ni–Ni bond lengths are 2.42 Å. All Ni–Ga bond lengths are 2.94 Å. In the second Ni site, Ni is bonded to four equivalent Ce, six Ni, and two equivalent Ga atoms to form distorted NiCe4Ga2Ni6 cuboctahedra that share corners with four equivalent GaCe3Ni9 cuboctahedra, corners with twenty NiCe3Ga3Ni6 cuboctahedra, edges with ten equivalent NiCe4Ga2Ni6 cuboctahedra, faces with six equivalent GaCe3Ni9 cuboctahedra, and faces with sixteen NiCe3Ga3Ni6 cuboctahedra. There are two shorter (2.50 Å) and two longer (2.59 Å) Ni–Ni bond lengths. Both Ni–Ga bond lengths are 2.45more »
