Conventional binary solid-state compounds AxBy form crystalline arrays of atoms A and B. Replacing the �atomic� building blocks by pseudo-spherical molecular clusters, analogous phases can form. Pseudo-spherical molecular clusters with diameters of the order of 1nm are truly mono-disperse and assemble into simple structures in analogy to well-known solid state compounds such as rock-salt or CdI2 type structures. In such molecular assemblies, the internal structure of the cluster remains unchanged, but charge is transferred between them. The Chevrel-type Co6Se8(Pet3)6 cluster combines with the C60 cluster to form a [Co6Se8(Pet3)6][C60]2 pseudo-binary molecular compound that has a significant charge transfer.
