In the first Er site, Er is bonded in a 12-coordinate geometry to twelve Fe atoms. There are a spread of Er–Fe bond distances ranging from 2.89–3.04 Å. In the second Er site, Er is bonded in a 12-coordinate geometry to twelve Fe atoms. There are a spread of Er–Fe bond distances ranging from 2.89–3.04 Å. Y is bonded in a 12-coordinate geometry to twelve Fe atoms. There are a spread of Y–Fe bond distances ranging from 2.91–3.05 Å. There are ten inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Er, two equivalent Y, and eight Fe atoms to form FeY2Er2Fe8 cuboctahedra that share corners with four equivalent FeY2Er2Fe8 cuboctahedra and faces with eight equivalent FeYEr3Fe8 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.45–2.63 Å. In the second Fe site, Fe is bonded in a distorted q6 geometry to one Er, two equivalent Y, and nine Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.46–2.60 Å. In the third Fe site, Fe is bonded in a distorted q6more »« less
