Materials Data on YbB2Os by Materials Project

Abstract

YbOsB2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb2+ is bonded in a 5-coordinate geometry to one Os2- and four equivalent B atoms. The Yb–Os bond length is 2.89 Å. There are two shorter (2.64 Å) and two longer (2.66 Å) Yb–B bond lengths. Os2- is bonded in a 7-coordinate geometry to one Yb2+ and six equivalent B atoms. There are a spread of Os–B bond distances ranging from 2.22–2.27 Å. B is bonded in a 7-coordinate geometry to two equivalent Yb2+, three equivalent Os2-, and two equivalent B atoms. There is one shorter (1.77 Å) and one longer (1.86 Å) B–B bond length.
