Ionothermal methods were employed in the synthesis of two novel uranyl coordination compounds: [C5H6N]2 [UO2(C7H7SO3)4(H2O)] (1) and UO2(HAsO4)(NC5H11O2) (2), using pyridinium and betainium class ionic liquids. The results show novel ionic liquid incorporation and uranyl structural topologies, providing insight into the development of low-dimensionality uranyl complexes beyond traditional hydrothermal methods.
