Materials Data on Tb4Ni3Bi8 by Materials Project

Abstract

Tb4Ni3Bi8 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 12-coordinate geometry to four equivalent Ni and eight Bi atoms. All Tb–Ni bond lengths are 3.11 Å. There are four shorter (3.29 Å) and four longer (3.43 Å) Tb–Bi bond lengths. In the second Tb site, Tb is bonded in a 11-coordinate geometry to two equivalent Ni and nine Bi atoms. Both Tb–Ni bond lengths are 3.10 Å. There are four shorter (3.31 Å) and five longer (3.41 Å) Tb–Bi bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded in a body-centered cubic geometry to four equivalent Tb and four equivalent Bi atoms. All Ni–Bi bond lengths are 2.67 Å. In the second Ni site, Ni is bonded in a body-centered cubic geometry to four equivalent Tb and four equivalent Bi atoms. All Ni–Bi bond lengths are 2.62 Å. There are four inequivalent Bi sites. In the first Bi site, Bi is bonded in a 7-coordinate geometry to five equivalent Tb and two equivalent Ni atoms. In the second Bi site, Bi is bonded in a 9-coordinate geometry to four equivalent Tb and four equivalent Ni atoms. In the third Bi site, Bi is bonded in a 8-coordinate geometry to four Tb and four equivalent Bi atoms. All Bi–Bi bond lengths are 3.21 Å. In the fourth Bi site, Bi is bonded in a 8-coordinate geometry to four Tb and four equivalent Bi atoms.
