Spontaneous self assembly reaction of [-Fe(CN)6]3- building blocks and R3Sn+ ions (R = alkyl or aryl) affords three-dimensional (3D) supramolecular [(R3Sn)3Fe(CN)6]n products, which were confirmed by different spectral data. The architecture of these supramolecular complexes involve guest-free cyanide-bridged 3D neutral networks. They are composed of nearly plannar R3Sn+ units, linked together with slightly distorted octahedral building blocks [-Fe(CN)6]3- through the cyanide N atoms. Pyridine compounds, acting as guest donors, have been successfully encapsulated within the expandable wide cavities of the 3D-supramolecular complexes by tribochemical reactions. This produces novel charge transfer molecular composites. The properties of the resulting molecular composites were investigated by elemental analyses, IR, UV-visible, X-ray powder diffraction, EPR and magnetic moments. The interesting feature of these molecular composites are their semiconductive properties.
