Title: Materials Data on Ho2CuGe4 by Materials Project

Abstract

Ho2CuGe4 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ho–Ge bond distances ranging from 3.00–3.16 Å. In the second Ho site, Ho is bonded in a 8-coordinate geometry to four equivalent Cu and ten Ge atoms. All Ho–Cu bond lengths are 3.11 Å. There are a spread of Ho–Ge bond distances ranging from 3.08–3.33 Å. Cu is bonded in a 9-coordinate geometry to four equivalent Ho and five Ge atoms. There are a spread of Cu–Ge bond distances ranging from 2.34–2.46 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four Ho, two equivalent Cu, and four equivalent Ge atoms. All Ge–Ge bond lengths are 2.86 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four Ho, two equivalent Cu, and four equivalent Ge atoms. In the third Ge site, Ge is bonded in a 1-coordinate geometry to six Ho, one Cu, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.53 Å.more » In the fourth Ge site, Ge is bonded in a 8-coordinate geometry to six Ho and two equivalent Ge atoms.« less
