Abstract: The anhydrous pyrocarbonate and the first hydrogen pyrocarbonate Li[HC$_2$O$_5$] have been synthesized in a laser-heated diamond anvil cell at moderate pressures ($\approx$ equation  GPa). The structures of the two compounds have been obtained from single crystal X-ray diffraction data. Raman spectroscopy and DFT calculations have been employed to further characterize their structure-property relations. The present results significantly enlarge the group of inorganic pyrocarbonates by the discovery of the hydrogenated pyrocarbonate anion Li[HC$_2$O$_5$]$^−$. In the structure of Li[HC$_2$O$_5$] there is a symmetric O−H−O arrangement at high pressures, which converts to a conventional O−Hmathematical equation O hydrogen bond upon pressure release.
