Materials Data on Zn13Rh by Materials Project

RhZn13 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Rh is bonded to twelve Zn atoms to form corner-sharing RhZn12 cuboctahedra. There are a spread of Rh–Zn bond distances ranging from 2.58–2.69 Å. There are five inequivalent Zn sites. In the first Zn site, Zn is bonded in a distorted linear geometry to two equivalent Rh and two equivalent Zn atoms. Both Zn–Zn bond lengths are 2.79 Å. In the second Zn site, Zn is bonded in a 1-coordinate geometry to one Rh and four Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.60–2.84 Å. In the third Zn site, Zn is bonded in a 1-coordinate geometry to one Rh and four Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.65–2.85 Å. In the fourth Zn site, Zn is bonded in a 1-coordinate geometry to one Rh and ten Zn atoms. The Zn–Zn bond length is 2.59 Å. In the fifth Zn site, Zn is bonded in a 10-coordinate geometry to ten Zn atoms. The Zn–Zn bond length is 2.72 Å.
