Materials Data on Zn5(BRh2)4 by Materials Project

Abstract

Zn5(Rh2B)4 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are three inequivalent Rh sites. In the first Rh site, Rh is bonded in a 4-coordinate geometry to four equivalent Zn and four equivalent B atoms. All Rh–Zn bond lengths are 2.85 Å. All Rh–B bond lengths are 2.22 Å. In the second Rh site, Rh is bonded in a distorted body-centered cubic geometry to six Zn and two equivalent B atoms. There are a spread of Rh–Zn bond distances ranging from 2.61–2.74 Å. Both Rh–B bond lengths are 2.13 Å. In the third Rh site, Rh is bonded in a distorted body-centered cubic geometry to four equivalent Zn and four equivalent B atoms. All Rh–Zn bond lengths are 2.72 Å. All Rh–B bond lengths are 2.23 Å. There are three inequivalent Zn sites. In the first Zn site, Zn is bonded in a 12-coordinate geometry to eight Rh atoms. In the second Zn site, Zn is bonded in a 11-coordinate geometry to eight Rh, one Zn, and two equivalent B atoms. The Zn–Zn bond length is 2.49 Å. Both Zn–B bond lengths are 2.69 Å. In the third Zn site, Zn is bonded in a body-centered cubic geometry to eight equivalent Rh atoms. B is bonded in a 6-coordinate geometry to six Rh and one Zn atom.
