Materials Data on B5Mo2 by Materials Project
Mo2B5 is Tungsten boride-like structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Mo+4.50+ is bonded in a 10-coordinate geometry to thirteen B+1.80- atoms. There are a spread of Mo–B bond distances ranging from 2.34–2.65 Å. There are three inequivalent B+1.80- sites. In the first B+1.80- site, B+1.80- is bonded in a 3-coordinate geometry to six equivalent Mo+4.50+ and three equivalent B+1.80- atoms. All B–B bond lengths are 1.78 Å. In the second B+1.80- site, B+1.80- is bonded in a 10-coordinate geometry to four equivalent Mo+4.50+ and six B+1.80- atoms. There is three shorter (1.82 Å) and three longer (1.94 Å) B–B bond length. In the third B+1.80- site, B+1.80- is bonded in a distorted hexagonal planar geometry to six equivalent Mo+4.50+ and six equivalent B+1.80- atoms.
