Materials Data on TmB2Os by Materials Project
TmOsB2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm3+ is bonded in a 8-coordinate geometry to eight equivalent B3- atoms. There are a spread of Tm–B bond distances ranging from 2.58–2.91 Å. Os3+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. There are a spread of Os–B bond distances ranging from 2.24–2.26 Å. B3- is bonded in a 9-coordinate geometry to four equivalent Tm3+, three equivalent Os3+, and two equivalent B3- atoms. There is one shorter (1.78 Å) and one longer (1.89 Å) B–B bond length.
