Tripraseodymium penta­iron(III) dodeca­oxide, Pr(3)Fe(5)O(12): a synchrotron radiation study

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 [Image: see text] site symmetry. The other Fe atom is coordinated b...

Descripción
Sumario: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 [Image: see text] site symmetry. The other Fe atom is coordinated by four O atoms, forming a slightly distorted tetra­hedron, and has [Image: see text] site symmetry. FeO(6) octa­hedra and FeO(4) 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.
