Materials Data on U(GeRh)2 by Materials Project

Abstract

URh2Ge2 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 6-coordinate geometry to six Rh atoms. There are a spread of U–Rh bond distances ranging from 2.25–2.91 Å. In the second U site, U is bonded in a 10-coordinate geometry to four equivalent Rh and six Ge atoms. All U–Rh bond lengths are 2.82 Å. There are a spread of U–Ge bond distances ranging from 2.64–2.88 Å. There are three inequivalent Rh sites. In the first Rh site, Rh is bonded in a distorted single-bond geometry to one U, four equivalent Rh, and four equivalent Ge atoms. All Rh–Rh bond lengths are 2.75 Å. All Rh–Ge bond lengths are 2.96 Å. In the second Rh site, Rh is bonded in a distorted single-bond geometry to one U and four equivalent Ge atoms. All Rh–Ge bond lengths are 2.81 Å. In the third Rh site, Rh is bonded in a 9-coordinate geometry to four U, two equivalent Rh, and three Ge atoms. There are one shorter (2.66 Å) and two longer (2.87 Å) Rh–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent U, five Rh, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.80 Å. In the second Ge site, Ge is bonded in a 6-coordinate geometry to one U, four equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.32 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to one U and five Ge atoms.
