Materials Data on U2Zn17 by Materials Project
U2Zn17 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 12-coordinate geometry to eighteen Zn atoms. There are a spread of U–Zn bond distances ranging from 3.14–3.48 Å. In the second U site, U is bonded in a 8-coordinate geometry to twenty Zn atoms. There are a spread of U–Zn bond distances ranging from 3.08–3.40 Å. There are four inequivalent Zn sites. In the first Zn site, Zn is bonded to two U and ten Zn atoms to form a mixture of distorted corner, edge, and face-sharing ZnU2Zn10 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.61–2.99 Å. In the second Zn site, Zn is bonded to two equivalent U and ten Zn atoms to form a mixture of distorted corner, edge, and face-sharing ZnU2Zn10 cuboctahedra. There are four shorter (2.64 Å) and two longer (2.74 Å) Zn–Zn bond lengths. In the third Zn site, Zn is bonded in a 12-coordinate geometry to three U and nine Zn atoms. There are two shorter (2.55 Å) and one longer (2.89 Å) Zn–Zn bond lengths. In the fourth Zn site, Zn is bonded in a 2-coordinate geometry to one U and thirteen Zn atoms. The Zn–Zn bond length is 2.64 Å.
