Trineodymium(III) pentairon(III) dodecaoxide, Nd3Fe5O12

The title compound, Nd3Fe5O12 (NdIG), has an iron garnet structure. One of the Fe atoms is coordinated by six O atoms in a slightly distorted octahedral geometry and has overline{3} site symmetry. The other Fe atom is coordinated by four O atoms in a slightly distorted tetrahedral geometry and has overline{4} site symmetry. The FeO6 octahedron and FeO4 tetrahedron are linked together by corners. The Nd atom is coordinated by eight O atoms in a distorted dodecahedral geometry and has 222 site symmetry. The O atoms occupy general positions.
