Spontaneous self-assembly of [Fe(CN)6]4- andR3Sn+ ions (R = Me, n-Bu or Ph) in the absence or presence of uncharged bidentate ligands (such as dioxane (diox), methylpyrazine (Mepyz), or 4,4_-bipyridine (bpy)) affords white precipitates. The products with the general composition [(R3Sn)4Fe(CN)6_2H2O_2L]; 2L = diox, Mepyz or bpy, have been obtained as host-guest polymeric architecture. The new compounds have been compared with their hydrated systems [(Me3Sn)4Fe(CN)6_xH2O]; x = 2 or 4 and with the water-free [(Me3Sn)4Fe(CN)6]. Results of extensive spectroscopic investigations (IR studies and X-ray powder diffractometry) suggest that the architecture of the novel host-guest systems involve three-dimensional networks, notably different from those of their parent system (containing fourH2Omolecules). These compounds show no ion-exchange activity towards NH4 + cations and are affected by moderate temperature. Also, these 3D-host-guest polymeric systems exhibit a high sensitivity to pH of the media.
