Materials Data on Ce(NiSb)2 by Materials Project

CeNi2Sb2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ce3+ is bonded to eight equivalent Sb3- atoms to form distorted edge-sharing CeSb8 hexagonal bipyramids. All Ce–Sb bond lengths are 3.31 Å. Ni+1.50+ is bonded in a 4-coordinate geometry to four equivalent Sb3- atoms. All Ni–Sb bond lengths are 2.57 Å. Sb3- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent Ni+1.50+ atoms.

Materials Data on Ce(NiSb)2 by Materials Project

CeNi2Sb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce3+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.36 Å) and four longer (3.41 Å) Ce–Sb bond lengths. There are two inequivalent Ni+1.50+ sites. In the first Ni+1.50+ site, Ni+1.50+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing NiSb4 tetrahedra. All Ni–Sb bond lengths are 2.57 Å. In the second Ni+1.50+ site, Ni+1.50+ is bonded in a 5-coordinate geometry to five Sb3- atoms. There are one shorter (2.49 Å) and four longer (2.53 Å) Ni–Sb bond lengths. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 4-coordinate geometry to four equivalent Ce3+ and four equivalent Ni+1.50+ atoms. In the second Sb3- site, Sb3- is bonded in a 9-coordinate geometry to four equivalent Ce3+ and five Ni+1.50+ atoms.
