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
