✦ Synopsis

Liquid XeF2 at 140-150' oxidizes PtF4: 5XeF2 f 2PtF4 -2Xe2F3PtF6 + Xe f. The salt Xe2F3+PtF6-loses XeF2 at 70" in vacua: --Xe2F3PtF6-XeFPtF6 + XeF2 f. Pyrolysis of XeF+PtF6at 150-160" yields XeF4: XeFPtF6 -XePt2FlO + XeF4 f. The complex XePt2F10 loses XeF2 at 430": XePt2FlO +PtF4 + XeF2 +. XePt2Flo also can be oxidized by liquid XeF2 at 140-150": XePt2FlO + 4XeF2-2Xe2F3PtF6 + Xe +. The paramagnetic mixed-valence fluoride Pd2F6 is oxidized by XeF2(R) at 140-150°: Pd2F6 + 3XeF2-2XePdF6 + Xe+. The yellow diamagnetic XePdF6, which is thermally stable at room temperature, loses XeF2 at 140-150": 2XePdF6 -XePd2FlO + XeF2 $. Both XePdF6 and XePd2FlO may be derived from XeF2 + PdF4. The complex XePd2FlO is a close structural relative of XePt2F10 and spectroscopic evidence suggests that both are salts of XeF+ and a polymeric (M2Fg)xX-ion. Pyrolysis of XePd2FlO at 280" yields XeF4: XePd2F10-Pd2F6 + XeF4.
