Materials Data on UB4W by Materials Project
UWB4 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 2.66–2.80 Å. W2+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of W–B bond distances ranging from 2.34–2.43 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 W2+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.75–1.89 Å. In the second B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent U4+, two equivalent W2+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.74–1.87 Å. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent U4+, two equivalent W2+, and three B+1.50- atoms. In the fourth B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to two equivalent U4+, four equivalent W2+, and three B+1.50- atoms. The B–B bond length is 1.76 Å.
