Materials Data on HoB7Mo3 by Materials Project
Abstract
HoMo3B7 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ho3+ is bonded in a 12-coordinate geometry to thirteen B+1.29- atoms. There are a spread of Ho–B bond distances ranging from 2.68–3.34 Å. There are three inequivalent Mo2+ sites. In the first Mo2+ site, Mo2+ is bonded to twelve B+1.29- atoms to form face-sharing MoB12 cuboctahedra. There are a spread of Mo–B bond distances ranging from 2.37–2.49 Å. In the second Mo2+ site, Mo2+ is bonded in a 9-coordinate geometry to nine B+1.29- atoms. There are a spread of Mo–B bond distances ranging from 2.24–2.33 Å. In the third Mo2+ site, Mo2+ is bonded in a 9-coordinate geometry to nine B+1.29- atoms. There are a spread of Mo–B bond distances ranging from 2.24–2.35 Å. There are seven inequivalent B+1.29- sites. In the first B+1.29- site, B+1.29- is bonded in a 9-coordinate geometry to one Ho3+, five Mo2+, and three B+1.29- atoms. There is two shorter (1.81 Å) and one longer (1.85 Å) B–B bond length. In the second B+1.29- site, B+1.29- is bonded in a 2-coordinate geometry to two equivalent Ho3+, five Mo2+, and two equivalent B+1.29- atoms. Both B–B bond lengths are 1.80 Å. In the thirdmore »
