Materials Data on Er3Ru2 by Materials Project

Er3Ru2 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Er is bonded in a 5-coordinate geometry to five Ru atoms. There are a spread of Er–Ru bond distances ranging from 2.90–3.11 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded in a body-centered cubic geometry to six equivalent Er and two equivalent Ru atoms. Both Ru–Ru bond lengths are 2.36 Å. In the second Ru site, Ru is bonded in a 9-coordinate geometry to nine equivalent Er atoms.

Materials Data on ErRu3 by Materials Project

ErRu3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er is bonded to twelve Ru atoms to form a mixture of edge, corner, and face-sharing ErRu12 cuboctahedra. There are four shorter (2.84 Å) and eight longer (2.86 Å) Er–Ru bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded to four equivalent Er atoms to form a mixture of distorted edge and corner-sharing RuEr4 cuboctahedra. In the second Ru site, Ru is bonded in a distorted square co-planar geometry to four equivalent Er atoms.
