Materials Data on Y2Ge5Ir3 by Materials Project

Abstract

Y2Ir3Ge5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Y is bonded in a 1-coordinate geometry to seven Ir and ten Ge atoms. There are a spread of Y–Ir bond distances ranging from 3.13–3.57 Å. There are a spread of Y–Ge bond distances ranging from 2.97–3.37 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 6-coordinate geometry to four equivalent Y and six Ge atoms. There are four shorter (2.54 Å) and two longer (2.64 Å) Ir–Ge bond lengths. In the second Ir site, Ir is bonded in a 10-coordinate geometry to five equivalent Y and five Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.39–2.53 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Y, three Ir, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.70 Å. In the second Ge site, Ge is bonded in a 3-coordinate geometry to four equivalent Y, three Ir, and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Y and four equivalent Ir atoms.
