Abstract

The new complex indium rhenium and scandium rhenium oxides, In6ReO12 and Sc6ReO12, have been synthesized as single phases in sealed silica tubes and by high-pressure high-temperature syntheses, and their crystal structures have been determined by single crystal X-ray diffraction.The compounds crystallize in a rhombohedral structure related to the distorted fluorite structure like Ln6ReO12 for some rare earth elements, S. G.: R-3, Z=3, aH= 9.248(2) Å, cH=8.720(2) Å for Sc6ReO12 and aH=9.492(1) Å, cH=8.933(1) Å for In6ReO12. A maximum in magnetization is observed for Sc6ReO12 at T(Mmax)=1.89(2) K, whereas ferromagnetic ordering is found for In6ReO12 by a pronounced increase in the temperature dependence of magnetization at TC=7.5(5) K. The magnetic moment per rhenium ion in In6ReO12 and Sc6ReO12 is 0.84(1) and 0.65(1) μB, respectively, derived from the paramagnetic regions.
