title: Tripraseodymium penta-iron(III) dodeca-oxide, Pr(3)Fe(5)O(12): a synchrotron radiation study.
abstract: The title compound, penta-iron tripraseodymium dodeca-oxide (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 octa-hedron, and has site symmetry. The other Fe atom is coordinated by four O atoms, forming a slightly distorted tetra-hedron, and has site symmetry. FeO(6) octa-hedra and FeO(4) tetra-hedra are linked together by corners. The Pr atom is coordinated by eight O atoms, forming a distorted dodeca-hedron, and has 222 site symmetry. The O atoms occupy the general positions.
