Materials Data on B2MoRu by Materials Project
MoRuB2 is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Mo3+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Mo–B bond distances ranging from 2.31–2.51 Å. Ru3+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of Ru–B bond distances ranging from 2.28–2.63 Å. There are two inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to three equivalent Mo3+, four equivalent Ru3+, and two equivalent B3- atoms. Both B–B bond lengths are 1.78 Å. In the second B3- site, B3- is bonded in a 9-coordinate geometry to four equivalent Mo3+, three equivalent Ru3+, and two equivalent B3- atoms.
