Materials Data on Nd3Y3(Fe5O12)2 by Materials Project
Nd3Y3(Fe5O12)2 crystallizes in the cubic I4_132 space group. The structure is three-dimensional. Nd3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.44 Å) and four longer (2.54 Å) Nd–O bond lengths. Y3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.39 Å) and four longer (2.49 Å) Y–O bond lengths. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. All Fe–O bond lengths are 2.06 Å. In the second Fe3+ site, Fe3+ is bonded to four O2- atoms to form corner-sharing FeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–54°. All Fe–O bond lengths are 1.90 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Y3+ and two Fe3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Nd3+ and two Fe3+ atoms.
