Synthesis and crystal structure of ABW-type SrFe(1.40)V(0.60)O(4)
Single crystals of SrFe(1.40)V(0.60)O(4), strontium tetraoxidodi[ferrate(III)/vanadate(III)], have been obtained as a side product in the course of sinter experiments aimed at the synthesis of double perovskites in the system SrO–Fe(2)O(3)–V(2)O(5). The crystal structure can be characterized by la...

Sumario: | Single crystals of SrFe(1.40)V(0.60)O(4), strontium tetraoxidodi[ferrate(III)/vanadate(III)], have been obtained as a side product in the course of sinter experiments aimed at the synthesis of double perovskites in the system SrO–Fe(2)O(3)–V(2)O(5). The crystal structure can be characterized by layers of six-membered rings of TO(4)-tetrahedra (T: Fe(III), V(III)) perpendicular to [100]. Stacking of the layers along [100] results in a three-dimensional framework enclosing tunnel-like cavities in which Sr(II) cations are incorporated for charge compensation. The sequence of directedness of up (U) and down (D) pointing vertices of neighboring tetrahedra in a single six-membered ring is UUUDDD. The topology of the tetrahedral framework belongs to the zeolite-type ABW. |
