Materials Data on Ho2Ge5Ru3 by Materials Project

Abstract

Ho2Ru3Ge5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Ho is bonded in a 1-coordinate geometry to six Ru and ten Ge atoms. There are four shorter (3.20 Å) and two longer (3.47 Å) Ho–Ru bond lengths. There are a spread of Ho–Ge bond distances ranging from 2.97–3.47 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded in a 6-coordinate geometry to four equivalent Ho and six Ge atoms. There are four shorter (2.51 Å) and two longer (2.60 Å) Ru–Ge bond lengths. In the second Ru site, Ru is bonded in a 9-coordinate geometry to four equivalent Ho and five Ge atoms. There are a spread of Ru–Ge bond distances ranging from 2.42–2.51 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to four equivalent Ho and four equivalent Ru atoms. In the second Ge site, Ge is bonded in a 11-coordinate geometry to four equivalent Ho, three Ru, and four Ge atoms. There are two shorter (2.70 Å) and two longer (2.88 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 6-coordinate geometry to four equivalent Ho, three Ru, and two equivalent Ge atoms.
