Materials Data on ErGe2Os by Materials Project
ErOsGe2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 12-coordinate geometry to four Os and eight Ge atoms. There are a spread of Er–Os bond distances ranging from 3.17–3.25 Å. There are a spread of Er–Ge bond distances ranging from 2.83–3.11 Å. In the second Er site, Er is bonded in a 7-coordinate geometry to six Os and seven Ge atoms. There are a spread of Er–Os bond distances ranging from 3.22–3.34 Å. There are a spread of Er–Ge bond distances ranging from 2.91–3.08 Å. There are two inequivalent Os sites. In the first Os site, Os is bonded in a 12-coordinate geometry to five Er, one Os, and six Ge atoms. The Os–Os bond length is 2.90 Å. There are a spread of Os–Ge bond distances ranging from 2.48–2.75 Å. In the second Os site, Os is bonded in a 12-coordinate geometry to four Er, two equivalent Os, and six Ge atoms. There are a spread of Os–Ge bond distances ranging from 2.58–2.66 Å. There are five inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to five Er and four Os atoms. In the second Ge site, Ge is bonded in a 7-coordinate geometry to three Er, three Os, and one Ge atom. The Ge–Ge bond length is 2.53 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Er, two equivalent Os, and one Ge atom. The Ge–Ge bond length is 2.66 Å. In the fourth Ge site, Ge is bonded in a 9-coordinate geometry to six Er, two equivalent Os, and one Ge atom. The Ge–Ge bond length is 2.62 Å. In the fifth Ge site, Ge is bonded in a 6-coordinate geometry to two equivalent Er and four Os atoms.
