Materials Data on UCoB4 by Materials Project
Abstract
UCoB4 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 2.57–2.70 Å. Co2+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Co–B bond distances ranging from 2.23–2.27 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 Co2+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.77–1.82 Å. In the second B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent U4+, two equivalent Co2+, and three B+1.50- atoms. There is one shorter (1.74 Å) and one longer (1.76 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 Co2+, and three B+1.50- atoms. There is one shorter (1.71 Å) and one longer (1.75 Å) B–B bond length. In the fourth B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent U4+, two equivalent Co2+, and three B+1.50- atoms.
