Abstract

U2Zn17 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. U is bonded in a 10-coordinate geometry to nineteen Zn atoms. There are a spread of U–Zn bond distances ranging from 3.12–3.43 Å. There are four inequivalent Zn sites. In the first Zn site, Zn is bonded to three equivalent U and nine Zn atoms to form distorted ZnU3Zn9 cuboctahedra that share corners with twenty-three ZnU2Zn10 cuboctahedra, edges with ten ZnU2Zn10 cuboctahedra, and faces with twenty ZnU3Zn9 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.54–2.86 Å. In the second Zn site, Zn is bonded in a 5-coordinate geometry to one U and thirteen Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.68–2.99 Å. In the third Zn site, Zn is bonded to two equivalent U and ten Zn atoms to form distorted ZnU2Zn10 cuboctahedra that share corners with twenty-two ZnU2Zn10 cuboctahedra, edges with ten ZnU2Zn10 cuboctahedra, and faces with eighteen ZnU3Zn9 cuboctahedra. All Zn–Zn bond lengths are 2.59 Å. In the fourth Zn site, Zn is bonded to two equivalent U and ten Zn atoms to form distorted ZnU2Zn10 cuboctahedra that share corners with twenty-four ZnU2Zn10 cuboctahedra, edges with fivemore »« less
