Materials Data on YbSb2 by Materials Project

Abstract

YbSb2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Yb3+ is bonded in a 10-coordinate geometry to ten Sb+1.50- atoms. There are a spread of Yb–Sb bond distances ranging from 3.23–3.60 Å. There are two inequivalent Sb+1.50- sites. In the first Sb+1.50- site, Sb+1.50- is bonded in a 4-coordinate geometry to six equivalent Yb3+ and two equivalent Sb+1.50- atoms. Both Sb–Sb bond lengths are 3.01 Å. In the second Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four equivalent Yb3+ and four equivalent Sb+1.50- atoms. All Sb–Sb bond lengths are 3.17 Å.
