Orthorhombic cerium(III) carbonate hydroxide studied by synchrotron powder X-ray diffraction
Cerium(III) carbonate is a precursor material for the synthesis of various Ce-containing compounds. In this work, a synchrotron powder X-ray diffraction study of commercially obtained 'cerium(III) carbonate hydrate' indicates that multiple Ce-containing phases are present. The majority phase CeCO<sub>3</sub>OH (52.49%<sub>wt</sub>) was refined using an ortho-rhom-bic <i>Pmcn</i> structure model with <i>a</i> = 5.01019 (2) Å, <i>b</i> = 8.55011 (4) Å and <i>c</i> = 7.31940 (4) Å, which is based on a reported structure for the lanthanoid carbonate mineral ancylite. Additionally, a substantial portion of the precursor material is cubic cerium(IV) oxide (47.12%<sub>wt</sub>).
