Title: Materials Data on UGe2Ir by Materials Project

Abstract

UIrGe2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 8-coordinate geometry to four equivalent Ir and ten Ge atoms. All U–Ir bond lengths are 3.20 Å. There are a spread of U–Ge bond distances ranging from 3.25–3.39 Å. In the second U site, U is bonded in a 8-coordinate geometry to six equivalent Ir and eight Ge atoms. There are four shorter (3.23 Å) and two longer (3.25 Å) U–Ir bond lengths. There are a spread of U–Ge bond distances ranging from 2.98–3.05 Å. Ir is bonded in a 10-coordinate geometry to five U and five Ge atoms. There are four shorter (2.48 Å) and one longer (2.62 Å) Ir–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 3-coordinate geometry to four equivalent U, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.41 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six U, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.42 Å. In the third Gemore » site, Ge is bonded in a 8-coordinate geometry to four U, three equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.70 Å.« less
