Synthesis, Structural, Magnetic, and Electronic Properties of Cubic CsMnMoO<sub>3</sub>F<sub>3</sub> Oxyfluoride
A powder sample of CsMnMoO<sub>3</sub>F<sub>3</sub> oxyfluoride
has been prepared by solid state synthesis. The pyrochlore-related
crystal structure of CsMnMoO<sub>3</sub>F<sub>3</sub> has been refined
by the Rietveld method at <i>T</i> = 298 K (space group <i>Fd-</i>3<i>m</i>, <i>a</i> = 10.59141(4)
ร
, <i>V</i> = 1188.123(8) ร
<sup>3</sup>; <i>R</i><sub>B</sub> = 3.44%). The stability of the cubic phase
has been obtained over the temperature range <i>T</i> =
110โ293 K by heat capacity measurements. Magnetic properties
have been measured over the range of <i>T</i> = 2โ300
K. The electronic structure of CsMnMoO<sub>3</sub>F<sub>3</sub> has
been evaluated by X-ray photoelectron spectroscopy. Chemical bonding
effects have been discussed for all metal ions using binding energy
difference parameters and wide comparison with related oxides and
fluorides. The competition between O<sup>2โ</sup> and F<sup>โ</sup> ions for metal valence electrons has been found
