Materials Data on Ho5(Ge5Os2)2 by Materials Project
Ho5(Os2Ge5)2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are three inequivalent Ho sites. In the first Ho site, Ho is bonded in a 8-coordinate geometry to four equivalent Os and twelve Ge atoms. All Ho–Os bond lengths are 3.27 Å. There are eight shorter (2.98 Å) and four longer (3.38 Å) Ho–Ge bond lengths. In the second Ho site, Ho is bonded to four equivalent Os and eight Ge atoms to form distorted face-sharing HoGe8Os4 cuboctahedra. All Ho–Os bond lengths are 3.12 Å. There are a spread of Ho–Ge bond distances ranging from 2.88–3.11 Å. In the third Ho site, Ho is bonded in a 12-coordinate geometry to four equivalent Os and ten Ge atoms. All Ho–Os bond lengths are 3.30 Å. There are a spread of Ho–Ge bond distances ranging from 3.29–3.39 Å. Os is bonded in a 10-coordinate geometry to five Ho and five Ge atoms. There are a spread of Os–Ge bond distances ranging from 2.44–2.61 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Ho, two equivalent Os, and one Ge atom. The Ge–Ge bond length is 2.52 Å. In the second Ge site, Ge is bonded in a 2-coordinate geometry to five Ho, two equivalent Os, and one Ge atom. The Ge–Ge bond length is 2.58 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four Ho, two equivalent Os, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.94 Å.
