Materials Data on U3Co2Ge7 by Materials Project
U3Co2Ge7 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 10-coordinate geometry to four equivalent Co and ten Ge atoms. All U–Co bond lengths are 3.28 Å. There are a spread of U–Ge bond distances ranging from 3.07–3.23 Å. In the second U site, U is bonded to twelve Ge atoms to form a mixture of distorted corner and face-sharing UGe12 cuboctahedra. There are a spread of U–Ge bond distances ranging from 2.94–3.03 Å. Co is bonded in a 5-coordinate geometry to four equivalent U and five Ge atoms. All Co–Ge bond lengths are 2.31 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent U, one Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.55 Å. In the second Ge site, Ge is bonded in a distorted square co-planar geometry to four equivalent U atoms. In the third Ge site, Ge is bonded in a 12-coordinate geometry to four U and two equivalent Co atoms. In the fourth Ge site, Ge is bonded in a 12-coordinate geometry to four U and two equivalent Co atoms.
