[en] We recently identified a synthetic procedure for the
isolation of Keplerate structures based on the reaction of
multivalent heterometal centers with larger
polyoxomolybate(V/VI) units that coexist in a reaction
solution at a certain pH. This approach yielded Keplerate
clusters of the type {Mo72Mo8V22},[16] {Mo72V15Fe7Mo8}, and
{Mo72V11Fe11Mo8},[14] which were obtained as kinetic products
within minutes to a few hours following addition of KCl.
Herein, we demonstrate for an analogous reaction system,
how novel {Mo72Fe30} Keplerate species with partially reduced
{(Mo)Mo5} building blocks (Robin–Day class III) can be
identified, based on Raman spectroscopy time profiles of
acidified aqueous molybdate reaction solutions.

The recently published synthesis of {(WVI)WVI 5}-based Keplerate clusters, for example, the {Mo 72(Mo2)30} analogue [(WVI 6021(H2O)5(CH3COO)0.5)12(Mov2O4(CH3COO))30]4S- = {W 72(Mo2)30} (C. Schäffer, A. Merca, H. Bögge, A. M. Todea, M. L. Kistler, T. Liu, R. Thouvenot, P. Gouzerh, A. Müller, Angew. Chem. 2009, 121, 155-159;
Angew. Chem. Int. Ed. 2009, 48, 149-153
) indicates that magnetic derivatives of the type {WVI 72M30} also exist. The {WVI72V IV30} analogue of (Mo72V30)[ 11] with shorter V-V distances was indeed isolated shortly thereafter; see: A.M. Todea, A. Merca, H. Bögge, T. Glaser, L. Engelhardt, R. Prozorov, M. Luban, A. Müller, Chem. Commun. 2009, 3351 -3353; the average exchange, in this case mediated by O-W-O bridges, is reduced as well.

The distance between the center of gravity of the five equatorial MoO6 groups to the central sevenfold-coordinated molybdenum position amounts to 0.35-0.37 Å and defines the doming of the ((Mo)Mo5) groups.
