Materials Data on U2Ge3 by Materials Project

Abstract

U2Ge3 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. U is bonded in a 10-coordinate geometry to one U and nine Ge atoms. The U–U bond length is 2.68 Å. There are three shorter (2.93 Å) and six longer (3.12 Å) U–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six equivalent U and three equivalent Ge atoms. All Ge–Ge bond lengths are 2.61 Å. In the second Ge site, Ge is bonded in a 6-coordinate geometry to six equivalent U and two equivalent Ge atoms. Both Ge–Ge bond lengths are 3.06 Å. In the third Ge site, Ge is bonded in a 11-coordinate geometry to six equivalent U and five Ge atoms.
