Materials Data on Mn3B4Mo3 by Materials Project
Mo3Mn3B4 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Mo2+ sites. In the first Mo2+ site, Mo2+ is bonded in a distorted hexagonal planar geometry to six B3- atoms. There are two shorter (2.30 Å) and four longer (2.32 Å) Mo–B bond lengths. In the second Mo2+ site, Mo2+ is bonded in a distorted hexagonal planar geometry to six B3- atoms. There are four shorter (2.31 Å) and two longer (2.34 Å) Mo–B bond lengths. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a rectangular see-saw-like geometry to four B3- atoms. There are a spread of Mn–B bond distances ranging from 2.20–2.39 Å. In the second Mn2+ site, Mn2+ is bonded in a distorted hexagonal planar geometry to six B3- atoms. There are four shorter (2.21 Å) and two longer (2.22 Å) Mn–B bond lengths. There are three inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to six Mo2+, two equivalent Mn2+, and one B3- atom. The B–B bond length is 1.93 Å. In the second B3- site, B3- is bonded in a 9-coordinate geometry to four equivalent Mo2+, four Mn2+, and one B3- atom. In the third B3- site, B3- is bonded in a 9-coordinate geometry to four Mo2+, four Mn2+, and one B3- atom. The B–B bond length is 1.81 Å.
