Materials Data on Tb3Ir by Materials Project
Tb3Ir is Cementite structured and crystallizes in the orthorhombic Pnma 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 three equivalent Ir atoms. There are a spread of Tb–Ir bond distances ranging from 2.87–3.29 Å. In the second Tb site, Tb is bonded in a distorted bent 150 degrees geometry to two equivalent Ir atoms. There are one shorter (2.78 Å) and one longer (2.88 Å) Tb–Ir bond lengths. Ir is bonded in a 6-coordinate geometry to eight Tb atoms.
