Materials Data on EuSb2 by Materials Project
EuSb2 is Zirconium Disilicide structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Eu3+ is bonded in a 10-coordinate geometry to ten Sb+1.50- atoms. There are a spread of Eu–Sb bond distances ranging from 3.30–3.66 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 Eu3+ 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 Eu3+ and four equivalent Sb+1.50- atoms. There are two shorter (3.02 Å) and two longer (3.44 Å) Sb–Sb bond lengths.
