Materials Data on Er3Pt by Materials Project
Er3Pt 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 Pt atoms. There are a spread of Er–Pt bond distances ranging from 2.84–3.33 Å. In the second Er site, Er is bonded in a distorted bent 120 degrees geometry to two equivalent Pt atoms. There are one shorter (2.79 Å) and one longer (2.87 Å) Er–Pt bond lengths. Pt is bonded in a 6-coordinate geometry to eight Er atoms.
