Materials Data on TbAl by Materials Project

TbAl crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 2-coordinate geometry to eight Al atoms. There are a spread of Tb–Al bond distances ranging from 3.08–3.40 Å. In the second Tb site, Tb is bonded in a 6-coordinate geometry to eight Al atoms. There are a spread of Tb–Al bond distances ranging from 3.08–3.54 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded to eight Tb and four Al atoms to form a mixture of distorted corner, edge, and face-sharing AlTb8Al4 cuboctahedra. There are two shorter (2.74 Å) and two longer (2.82 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a 10-coordinate geometry to eight Tb and two equivalent Al atoms.
