Materials Data on Ho3Ge5 by Materials Project

Abstract

Ho3Ge5 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 8-coordinate geometry to ten Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.95–3.47 Å. In the second 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 2.94–3.46 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to six Ho and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.60 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to six Ho and two equivalent Ge atoms. There are one shorter (2.58 Å) and one longer (2.63 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 9-coordinate geometry to six Ho and three Ge atoms.
