Title: Materials Data on U3Co4Ge7 by Materials Project

Abstract

U3Co4Ge7 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded to twelve Ge atoms to form a mixture of distorted corner and face-sharing UGe12 cuboctahedra. There are four shorter (2.93 Å) and eight longer (3.04 Å) U–Ge bond lengths. In the second U site, U is bonded in a 12-coordinate geometry to eight Co and eight Ge atoms. There are four shorter (2.95 Å) and four longer (3.29 Å) U–Co bond lengths. There are four shorter (3.04 Å) and four longer (3.26 Å) U–Ge bond lengths. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 8-coordinate geometry to four equivalent U and four equivalent Ge atoms. All Co–Ge bond lengths are 2.44 Å. In the second Co site, Co is bonded in a 5-coordinate geometry to four equivalent U and five Ge atoms. There are four shorter (2.30 Å) and one longer (2.32 Å) Co–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a square co-planar geometry to four equivalent U atoms. In the second Ge site, Gemore » is bonded in a 2-coordinate geometry to four U and two equivalent Co atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent U and five Co atoms.« less
