Materials Data on UB4Ru by Materials Project
URuB4 crystallizes in the orthorhombic Cmmm 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 2.63–2.75 Å. Ru2+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Ru–B bond distances ranging from 2.26–2.40 Å. There are three 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 Ru2+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.74–1.88 Å. In the second B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent U4+, two equivalent Ru2+, and three B+1.50- atoms. The B–B bond length is 1.76 Å. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to two equivalent U4+, four equivalent Ru2+, and three B+1.50- atoms. The B–B bond length is 1.74 Å.
