Title: Materials Data on Ho4Ge9Ir13 by Materials Project

Abstract

Ho4Ir13Ge9 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are three inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to ten Ir and six Ge atoms. There are a spread of Ho–Ir bond distances ranging from 3.06–3.51 Å. All Ho–Ge bond lengths are 3.12 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to ten Ir and six Ge atoms. There are a spread of Ho–Ir bond distances ranging from 3.16–3.53 Å. There are a spread of Ho–Ge bond distances ranging from 3.08–3.17 Å. In the third Ho site, Ho is bonded in a 12-coordinate geometry to twelve Ir and six Ge atoms. There are a spread of Ho–Ir bond distances ranging from 3.16–3.53 Å. There are two shorter (3.08 Å) and four longer (3.13 Å) Ho–Ge bond lengths. There are eight inequivalent Ir sites. In the first Ir site, Ir is bonded to four Ho and four Ge atoms to form a mixture of distorted corner and edge-sharing IrHo4Ge4 tetrahedra. There are two shorter (2.48 Å) and two longer (2.50 Å) Ir–Ge bond lengths. In the second Ir site, Ir is bonded in amore » 3-coordinate geometry to six Ho and three Ge atoms. There are two shorter (2.41 Å) and one longer (2.43 Å) Ir–Ge bond lengths. In the third Ir site, Ir is bonded in a 5-coordinate geometry to two equivalent Ho and five Ge atoms. There are one shorter (2.48 Å) and four longer (2.62 Å) Ir–Ge bond lengths. In the fourth Ir site, Ir is bonded in a 4-coordinate geometry to three Ho and four Ge atoms. There are two shorter (2.48 Å) and two longer (2.54 Å) Ir–Ge bond lengths. In the fifth Ir site, Ir is bonded in a 12-coordinate geometry to three Ho and four Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.45–2.58 Å. In the sixth Ir site, Ir is bonded to four Ho and four Ge atoms to form a mixture of distorted corner, edge, and face-sharing IrHo4Ge4 tetrahedra. There are a spread of Ir–Ge bond distances ranging from 2.47–2.50 Å. In the seventh Ir site, Ir is bonded in a 12-coordinate geometry to three equivalent Ho and four Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.43–2.63 Å. In the eighth Ir site, Ir is bonded in a 5-coordinate geometry to two Ho and five Ge atoms. There are one shorter (2.49 Å) and four longer (2.61 Å) Ir–Ge bond lengths. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four Ho and five Ir atoms. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ho and six Ir atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Ho and seven Ir atoms. In the fourth Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Ho and seven Ir atoms. In the fifth Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ho and five Ir atoms. In the sixth Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ho and six Ir atoms.« less
