Materials Data on Er5Ru2 by Materials Project
Er5Ru2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded in a 2-coordinate geometry to three equivalent Ru atoms. There are a spread of Er–Ru bond distances ranging from 2.73–3.35 Å. In the second Er site, Er is bonded to four equivalent Ru atoms to form distorted edge-sharing ErRu4 tetrahedra. There are two shorter (2.86 Å) and two longer (2.91 Å) Er–Ru bond lengths. In the third Er site, Er is bonded in a 3-coordinate geometry to three equivalent Ru atoms. There are a spread of Er–Ru bond distances ranging from 2.82–3.00 Å. Ru is bonded in a 7-coordinate geometry to eight Er atoms.
