Tetravalent actinide peroxides and related structures have been very poorly reported in the literature. A combination of synchrotron XRD and EXAFS techniques allowed to solve the structure of an original Th peroxo sulfate dihydrate, Th(O 2 )(SO 4 )(H 2 O) 2 , which crystallizes in the Pna 2 1 space group of the orthorhombic system in the form of polymeric microfibres. Peroxide ligands coordinate to Th cations with a rare μ 3 –η 2 :η 2 :η 2 bridging mode, forming infinite 1D chains decorated simultaneously with monodentate and bidentate sulfato ligands.
