Materials Data on Tb5BiPt2 by Materials Project
Tb5Pt2Bi crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded to four equivalent Pt and two equivalent Bi atoms to form distorted corner-sharing TbBi2Pt4 octahedra. The corner-sharing octahedra tilt angles range from 0–48°. All Tb–Pt bond lengths are 3.04 Å. Both Tb–Bi bond lengths are 3.47 Å. In the second Tb site, Tb is bonded in a 5-coordinate geometry to three equivalent Pt and two equivalent Bi atoms. There are one shorter (2.96 Å) and two longer (2.99 Å) Tb–Pt bond lengths. Both Tb–Bi bond lengths are 3.36 Å. Pt is bonded in a 8-coordinate geometry to eight Tb atoms. Bi is bonded in a distorted q6 geometry to ten Tb atoms.
