Materials Data on Er3Ir by Materials Project
Er3Ir is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 2-coordinate geometry to three equivalent Ir atoms. There are a spread of Er–Ir bond distances ranging from 2.84–3.21 Å. In the second Er site, Er is bonded in a distorted bent 150 degrees geometry to two equivalent Ir atoms. There are one shorter (2.75 Å) and one longer (2.84 Å) Er–Ir bond lengths. Ir is bonded in a 6-coordinate geometry to eight Er atoms.
