Materials Data on Tm3Ir by Materials Project
Tm3Ir is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 2-coordinate geometry to three equivalent Ir atoms. There are a spread of Tm–Ir bond distances ranging from 2.84–3.19 Å. In the second Tm site, Tm is bonded in a distorted bent 150 degrees geometry to two equivalent Ir atoms. There are one shorter (2.75 Å) and one longer (2.81 Å) Tm–Ir bond lengths. Ir is bonded in a 6-coordinate geometry to eight Tm atoms.
