Materials Data on U3Ni3(SnSb)2 by Materials Project

Abstract

U3Ni3(SnSb)2 crystallizes in the cubic I2_13 space group. The structure is three-dimensional. U is bonded in a 12-coordinate geometry to four equivalent Ni, four equivalent Sn, and four equivalent Sb atoms. There are two shorter (2.84 Å) and two longer (2.85 Å) U–Ni bond lengths. There are two shorter (3.20 Å) and two longer (3.24 Å) U–Sn bond lengths. All U–Sb bond lengths are 3.22 Å. Ni is bonded in a 8-coordinate geometry to four equivalent U, two equivalent Sn, and two equivalent Sb atoms. Both Ni–Sn bond lengths are 2.62 Å. Both Ni–Sb bond lengths are 2.59 Å. Sn is bonded in a 9-coordinate geometry to six equivalent U and three equivalent Ni atoms. Sb is bonded in a 9-coordinate geometry to six equivalent U and three equivalent Ni atoms.
