Abstract
Section titled “Abstract”The synthesis of a novel type of carbonate, namely of the inorganic pyrocarbonate salt Sr[C<sub>2</sub>O<sub>5</sub>], which contains isolated [C<sub>2</sub>O<sub>5</sub>]<sup>2-</sup>-groups, significantly extends the crystal chemistry of inorganic carbonates beyond the established <i>sp</i><sup>2</sup>- and <i>sp</i><sup>3</sup>-carbonates. We synthesized Sr[C<sub>2</sub>O<sub>5</sub>] in a laser-heated diamond anvil cell by reacting Sr[CO<sub>3</sub>] with CO<sub>2</sub>. By single crystal synchrotron diffraction, Raman spectroscopy, and density functional theory (DFT) calculations, we show that it is a pyrocarbonate salt. Sr[C<sub>2</sub>O<sub>5</sub>] is the first member of a novel family of inorganic carbonates. We predict, based on DFT calculations, that further inorganic pyrocarbonates can be obtained and that these will be relevant to geoscience and may provide a better understanding of reactions converting CO<sub>2</sub> into useful inorganic compounds.
