Materials Data on ErB2Ru by Materials Project
ErRuB2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Er3+ is bonded in a 8-coordinate geometry to eight equivalent B3- atoms. There are a spread of Er–B bond distances ranging from 2.61–2.95 Å. Ru3+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. There are two shorter (2.24 Å) and four longer (2.27 Å) Ru–B bond lengths. B3- is bonded in a 9-coordinate geometry to four equivalent Er3+, three equivalent Ru3+, and two equivalent B3- atoms. There is one shorter (1.76 Å) and one longer (1.86 Å) B–B bond length.
