Tripraseodymium penta­iron(III) dodeca­oxide Pr3Fe5O12: a synchrotron radiation study

摘要

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.
