Aqueous Synthesis of Strontium Ruthenate(VI) Oxyhydroxides and Their Crystal Structure Solution from Microcrystals.

ABSTRACT: Investigation of the earliest stages of hydrothermal reactions between KRuO₄ and either Sr(NO₃)₂ or SrO₂ allows the isolation of phase-pure SrRuO₃(OH)₂, a hitherto uncharacterized Ru(VI) oxyhydroxide, previously mentioned in the literature as SrRuO₄·H₂O. Further exploration of synthesis conditions with excess of strontium salt yields a second Ru(VI) phase, Sr₃Ru₂O₈(OH)₂ at 200 °C. Both structures were solved by 3D-electron diffraction and refined using powder neutron diffraction (SrRuO₃(OH)₂: monoclinic P2₁/n, a = 9.9903(3) Å, b = 7.7023(2) Å, c = 17.3677(6) Å, β = 89.353(2)°; Sr₃Ru
