International audienceCalcium oxalate minerals of the general formula CaC2O4.xH2O are widely present in nature and usually associated with pathological calcifications, constituting up to 70−80% of the mineral component of renal calculi. The monohydrate phase (CaC2O4.H2O, COM) is the most stable form, accounting for the majority of the hydrated calcium oxalates found. These mineral phases have been studied extensively via X-ray diffraction and IRspectroscopy and, to a lesser extent, using 1H, 13C, and 43Ca solidstate NMR spectroscopy. However, several aspects of their structure and reactivity are still unclear, such as the evolution from low- to high-temperature COM structures (LT-COM and HT-COM, respectively) and the involvement of water mo...
