MIV molecular oxo-clusters of the f- and d-block (M=Zr, Hf, Ce, Th, U, Np, Pu) have been prolific in bottoms-up material design, catalysis, as well as understanding metal oxide assembly, dissolution and surface reactivity in nature and in synthesis. Here we introduce Ce70, a new CeIV wheel-shaped oxo-cluster, [CeIV(OH)36(O)64(SO4)60(H2O)10]4-, isostructural with prior-reported U70. Like U70, Ce70 crystallizes into intricate frameworks with divalent transition metal counter-cations (TMII), and also CeIV-monomer and sulfate addenda ions.
