Materials Data on Pu2Zn17 by Materials Project
Pu2Zn17 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Pu is bonded in a 10-coordinate geometry to nineteen Zn atoms. There are a spread of Pu–Zn bond distances ranging from 3.09–3.47 Å. There are four inequivalent Zn sites. In the first Zn site, Zn is bonded to two equivalent Pu and ten Zn atoms to form a mixture of distorted edge, corner, and face-sharing ZnPu2Zn10 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.60–2.74 Å. In the second Zn site, Zn is bonded to two equivalent Pu and ten Zn atoms to form a mixture of distorted edge, corner, and face-sharing ZnPu2Zn10 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.71–3.03 Å. In the third Zn site, Zn is bonded to three equivalent Pu and nine Zn atoms to form a mixture of distorted edge, corner, and face-sharing ZnPu3Zn9 cuboctahedra. There are two shorter (2.55 Å) and one longer (2.87 Å) Zn–Zn bond lengths. In the fourth Zn site, Zn is bonded in a 2-coordinate geometry to one Pu and thirteen Zn atoms. The Zn–Zn bond length is 2.69 Å.
