Materials Data on UB4Mo by Materials Project
UMoB4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. U4+ is bonded in a 2-coordinate geometry to fourteen B+1.50- atoms. There are a spread of U–B bond distances ranging from 2.67–2.81 Å. Mo2+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Mo–B bond distances ranging from 2.33–2.45 Å. There are four inequivalent B+1.50- sites. In the first B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent U4+, two equivalent Mo2+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.75–1.88 Å. In the second B+1.50- site, B+1.50- is bonded in a 3-coordinate geometry to four equivalent U4+, two equivalent Mo2+, and three B+1.50- atoms. There is one shorter (1.74 Å) and one longer (1.75 Å) B–B bond length. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to two equivalent U4+, four equivalent Mo2+, and three B+1.50- atoms. There is one shorter (1.75 Å) and one longer (1.77 Å) B–B bond length. In the fourth B+1.50- site, B+1.50- is bonded in a 3-coordinate geometry to four equivalent U4+, two equivalent Mo2+, and three B+1.50- atoms.
