In the third Ce site, Ce is bonded to four Ni, two equivalent Bi, and six Sb atoms to form distorted CeNi4Bi2Sb6 cuboctahedra that share corners with four equivalent CeNi4Bi2Sb6 cuboctahedra, corners with four equivalent BiCe4Sb4 hexagonal bipyramids, corners with four equivalent SbCe4Bi4 hexagonal bipyramids, edges with four equivalent CeNi4Bi2Sb6 cuboctahedra, edges with two equivalent BiCe4Sb4 hexagonal bipyramids, edges with two equivalent SbCe4Bi4 hexagonal bipyramids, and faces with four equivalent CeNi4Bi2Sb6 cuboctahedra. There are two shorter (3.15 Å) and two longer (3.16 Å) Ce–Ni bond lengths. Both Ce–Bi bond lengths are 3.42 Å. There are four shorter (3.29 Å) and two longer (3.43 Å) Ce–Sb bond lengths. In the fourth Ce site, Ce is bonded in a 12-coordinate geometry to four Ni, four Bi, and four equivalent Sb atoms. All Ce–Ni bond lengths are 3.10 Å. All Ce–Bi bond lengths are 3.48 Å. All Ce–Sb bond lengths are 3.28 Å. There are four inequivalent Ni sites. In the first Ni site, Ni is bonded in a distorted body-centered cubic geometry to four Ce and four Sb atoms. There are two shorter (2.61 Å) and two longer (2.62 Å) Ni–Sb bond lengths. In the second Ni site, Ni is bonded in a distorted body-centered cubic geometry to four Ce and four Sb atoms. There are two shorter (2.61 Å) and two longer (2.62 Å) Ni–Sb bond lengths. In the third Ni site, Ni is bonded in a distorted body-centered cubic geometry to four Ce and four Sb atoms. There are two shorter (2.61 Å) and two longer (2.62 Å) Ni–Sb bond lengths. In the fourth Ni site, Ni is bonded in a distorted body-centered cubic geometry to four Ce and four Sb atoms. All Ni–Sb bond lengths are 2.61 Å. There are three inequivalent Bi sites. In the first Bi site, Bi is bonded in a 8-coordinate geometry to four Ce and four equivalent Bi atoms.
