Popis:	New supramolecular complexes [(Me 3 Sn)(Ph 3 Sn) 2 Fe(CN) 6 ] (I) and [(n-Bu 3 Sn)(Ph 3 Sn) 2 Fe(CN) 6 ] (II) are readily accessible by straightforward self-assembly of [Fe(CN) 6 ] 3− and hydrated R 3 Sn+/R′ 3 Sn + ions (R = Ph, and R′ = Me or n-Bu). The structural characterization of (I) and (II) is compared with well-documented supramolecular complex containing only Ph 3 Sn + unit, [(Ph 3 Sn) 3 Fe(CN) 6 ]. These novel compounds have wide internal cavities capable of encapsulating voluminous organic compounds, and they behave as host acceptors forming charge transfer complexes (CTC). Thiophene compounds acting as guest donor species are encapsulated within the cavities of the three-dimensional (3D) supramolecular hosts. The structure and physical properties of these hosts and host–guest systems were studied by X-ray powder diffraction, IR, UV/Vis., and magnetic measurements.
