Sphere we go : A spherical capsule is prepared simply by the interaction of linkers to pentagonal structural units. The metal centers (M) of the {(Mo VI )Mo VI 5 } 12 M 30 type Keplerates formed (M=V IV , Fe III ) describe an icosidodecahedron (see picture). For M=Fe III the magnetic configuration of the 30 spin centers (colored spheres) can be pictured geometrically in terms of three sets, each of 10 spins, with different angular orientations (arrows). With M=V IV the compound behaves according to the demands of quantum mechanics and a clear geometrical picture of the magnetism is not possible.
