摘要：

The crystal structure of the strontium thallate SrTl2O4 was determined using powder X-ray diffraction. This oxide is isostructural with CaFe2O4, i.e. it crystallizes in the space group Pnam with a = 10.041 angstrom b = 11.697 angstrom and c = 3.409 angstrom. The [Tl2O4]infinity framework is built up from double rutile chains of TlO6 octahedra forming five-sided tunnels where the stontium cations are located. The semi metallic properties of this phase are once more in favour of the existence of proximity effect induced superconductivity in the [TlO]infinity layers of layered thallium cuprates.
