Materials Data on Zr9Pt11 by Materials Project
Zr9Pt11 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are three inequivalent Zr+2.44+ sites. In the first Zr+2.44+ site, Zr+2.44+ is bonded in a 9-coordinate geometry to nine Pt2- atoms. There are a spread of Zr–Pt bond distances ranging from 2.79–3.22 Å. In the second Zr+2.44+ site, Zr+2.44+ is bonded in a body-centered cubic geometry to eight Pt2- atoms. There are a spread of Zr–Pt bond distances ranging from 2.76–2.85 Å. In the third Zr+2.44+ site, Zr+2.44+ is bonded in a 10-coordinate geometry to ten Pt2- atoms. There are eight shorter (3.03 Å) and two longer (3.43 Å) Zr–Pt bond lengths. There are three inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in a 7-coordinate geometry to seven Zr+2.44+ atoms. In the second Pt2- site, Pt2- is bonded in a 8-coordinate geometry to eight Zr+2.44+ atoms. In the third Pt2- site, Pt2- is bonded in a distorted square co-planar geometry to six Zr+2.44+ atoms.
