Hydrated {Mo72Fe30} clusters: Low-frequency hydrogen modes and self-aggregation

The [Mo72Fe30O252(CH3COO)12[Mo2O7(H2O)]2[H2Mo2O8(H2O)](H2O)91]· ≈ 150 H2O has been studied using incoherent quasi-elastic and inelastic neutron scattering evidencing the nanocage confinement on both the hydrogen relaxational dynamics and hydrogen low-frequency modes. Aggregation in solution has been investigated by SAXS revealing the evolution from monomer to the “blackberry” structure.
