Abstract
The spherical capsule skeleton of the host–guest system [{Mo6O19}2−⊂{MoVI72FeIII30O252(CH3COO)20(H2O)92}]4−1a—built up by 12 {(MoVI)MoVI5} type pentagonal units linked by 30 FeIII centers which span the unique icosahedral Archimedean solid, the icosidodecahedron—can now be constructed deliberately and with a simpler composition than before from an acidified aqueous molybdate solution containing the mentioned (virtual) pentagonal units; the encapsulated hexamolybdate—normally not formed in
