Materials Data on EuGe2Ir by Materials Project

Abstract

EuIrGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to four equivalent Ir and ten Ge atoms. All Eu–Ir bond lengths are 3.36 Å. There are a spread of Eu–Ge bond distances ranging from 3.28–3.42 Å. Ir is bonded in a 9-coordinate geometry to four equivalent Eu and five Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.43–2.54 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Eu, one Ir, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.59 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Eu and four equivalent Ir atoms.
