Materials Data on HoAlB14 by Materials Project
Abstract
HoAlB14 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Ho3+ is bonded in a 12-coordinate geometry to sixteen B+0.43- atoms. There are a spread of Ho–B bond distances ranging from 2.54–2.84 Å. Al3+ is bonded to twelve B+0.43- atoms to form distorted face-sharing AlB12 cuboctahedra. There are a spread of Al–B bond distances ranging from 2.12–2.44 Å. There are five inequivalent B+0.43- sites. In the first B+0.43- site, B+0.43- is bonded in a 7-coordinate geometry to one Ho3+, two equivalent Al3+, and four B+0.43- atoms. There are a spread of B–B bond distances ranging from 1.75–2.25 Å. In the second B+0.43- site, B+0.43- is bonded in a 8-coordinate geometry to one Ho3+, one Al3+, and six B+0.43- atoms. There are a spread of B–B bond distances ranging from 1.76–1.86 Å. In the third B+0.43- site, B+0.43- is bonded in a 1-coordinate geometry to one Ho3+ and six B+0.43- atoms. There are a spread of B–B bond distances ranging from 1.74–1.84 Å. In the fourth B+0.43- site, B+0.43- is bonded in a 8-coordinate geometry to two equivalent Ho3+ and six B+0.43- atoms. There are a spread of B–B bond distances ranging from 1.78–1.92more »
