Abstract: The title compound, pentairon tripraseodymium dodecaoxide (PrIG), has an iron garnet structure. There are two Fe site symmetries. One of the Fe atoms is coordinated by six O atoms, forming a slightly distorted octahedron, and has 
site symmetry. The other Fe atom is coordinated by four O atoms, forming a slightly distorted tetrahedron, and has 
site symmetry. FeO6 octahedra and FeO4 tetrahedra are linked together by corners. The Pr atom is coordinated by eight O atoms, forming a distorted dodecahedron, and has 222 site symmetry. The O atoms occupy the general positions.
