Er9(FeGe)10 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are four inequivalent Er sites. In the first Er site, Er is bonded in a 7-coordinate geometry to four equivalent Fe and seven Ge atoms. There are two shorter (3.09 Å) and two longer (3.25 Å) Er–Fe bond lengths. There are a spread of Er–Ge bond distances ranging from 2.92–3.08 Å. In the second Er site, Er is bonded in a 7-coordinate geometry to five Fe and six Ge atoms. There are one shorter (2.95 Å) and four longer (3.13 Å) Er–Fe bond lengths. There are a spread of Er–Ge bond distances ranging from 2.82–3.09 Å. In the third Er site, Er is bonded in a 6-coordinate geometry to four equivalent Fe and six Ge atoms. All Er–Fe bond lengths are 3.15 Å. There are a spread of Er–Ge bond distances ranging from 2.89–3.21 Å. In the fourth Er site, Er is bonded in a 6-coordinate geometry to twelve Fe and two equivalent Ge atoms. There are four shorter (2.98 Å) and eight longer (3.20 Å) Er–Fe bond lengths. Both Er–Ge bond lengths are 2.93 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a 12-coordinate geometry to five Er, three Fe, and four Ge atoms. There are a spread of Fe–Fe bond distances ranging from 2.48–2.73 Å. There are a spread of Fe–Ge bond distances ranging from 2.47–2.56 Å. In the second Fe site, Fe is bonded in a 12-coordinate geometry to three Er, five Fe, and two equivalent Ge atoms. The Fe–Fe bond length is 2.61 Å. Both Fe–Ge bond lengths are 2.64 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to eight Er and two equivalent Ge atoms. There are one shorter (2.67 Å) and one longer (2.68 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 9-coordinate geometry to five Er and four equivalent Fe atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to five Er and four equivalent Fe atoms. In the fourth Ge site, Ge is bonded in a 10-coordinate geometry to four Er and six Fe atoms.
