Materials Data on DyB2Os by Materials Project

DyOsB2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Dy3+ is bonded in a 8-coordinate geometry to eight equivalent B3- atoms. There are a spread of Dy–B bond distances ranging from 2.62–2.93 Å. Os3+ is bonded in a 6-coordinate geometry to six equivalent B3- atoms. There are two shorter (2.25 Å) and four longer (2.27 Å) Os–B bond lengths. B3- is bonded in a 9-coordinate geometry to four equivalent Dy3+, three equivalent Os3+, and two equivalent B3- atoms. There is one shorter (1.79 Å) and one longer (1.90 Å) B–B bond length.
