  The crystal structure of Rb2SeO4 in its high-temperature phase is reported for the first time. Powder diffraction data collected at T = 898 K show that it is hexagonal (a = 6.3428(1) A, c = 8.5445(1) A, V = 297.71(1) A3, space group P63/mmc (194), Z = 2) and is isostructural to Tl2SeO4, thus belonging to the α-K2SO4 structure type. DSC measurements indicate that the phase transition occurs at T = 818 K.

  We describe an exploratory investigation of the structure and electronic properties of new ruthenium(IV) pyrochlore oxides and their manganese-substituted derivatives. Our investigations have revealed several, hitherto unreported, electronic ground states for these materials: a metallic and Pauli paramagnetic state for BiPbRu2O6.5 that turns into a semiconducting ferromagnetic spin-glass state at 50 K for BiPbRuMnO6.5; a metallic state that likely shows a charge density wave (CDW) instability at 50–225 K for Bi1.50Zn0.50Ru2O6.75 that is suppressed by manganese substitution in Bi1.50Zn0.50Ru1.75Mn0.25O6.50; and a metallic ferromagnetic spin-glass like state for Pb2Ru1.75Mn0.25O6.15. The results indeed affirm the richness of the electronic properties of ruthenium-based metal oxides.
