Materials Data on ErB2Ru3 by Materials Project
ErRu3B2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to two equivalent Er, twelve equivalent Ru, and six equivalent B atoms. Both Er–Er bond lengths are 3.03 Å. All Er–Ru bond lengths are 3.14 Å. All Er–B bond lengths are 3.17 Å. Ru is bonded in a distorted square co-planar geometry to four equivalent Er and four equivalent B atoms. All Ru–B bond lengths are 2.19 Å. B is bonded in a 6-coordinate geometry to three equivalent Er and six equivalent Ru atoms.
