N2 - The double oxalates MI3[MIII(C2O4)3] possess rich crystallochemistry and can be used as precursors for various ceramic materials. The article discusses a case of Li3[Al(C2O4)3]. A series of previously unknown hydrates (Li3[Al(C2O4)3] ⋅ 5.5H2O, Li3[Al(C2O4)3] ⋅ 4H2O, Li3[Al(C2O4)3] ⋅ H2O) was found for this composition, their crystal structure and temperatures of mutual transformations determined. Transformation from Li3[Al(C2O4)3] ⋅ 4H2O to Li3[Al(C2O4)3] ⋅ H2O was found to be accompanied by a change in the topology of the bonding network. Uniaxial negative thermal expansion was found for anhydrous Li3[Al(C2O4)3]. Thermal decomposition of Li3[Al(C2O4)3] was demonstrated to be a promising way to obtain precursors for aluminate ceramics. © 2024 Wiley-VCH GmbH.
