Materials Data on ZrBi2 by Materials Project

Abstract

Bi2Zr crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 8-coordinate geometry to eight Bi atoms. There are a spread of Zr–Bi bond distances ranging from 3.11–3.22 Å. In the second Zr site, Zr is bonded in a 8-coordinate geometry to eight Bi atoms. There are a spread of Zr–Bi bond distances ranging from 3.06–3.18 Å. There are four inequivalent Bi sites. In the first Bi site, Bi is bonded in a 3-coordinate geometry to three Zr and three Bi atoms. There are one shorter (3.13 Å) and two longer (3.24 Å) Bi–Bi bond lengths. In the second Bi site, Bi is bonded in a 3-coordinate geometry to three Zr atoms. In the third Bi site, Bi is bonded in a 4-coordinate geometry to four Zr and two equivalent Bi atoms. In the fourth Bi site, Bi is bonded in a 6-coordinate geometry to six Zr atoms.
