✦ Synopsis


The synthesis of the new symmetrical koiland 2 based on the double fusion of two p-ethylcalix [4]arene in cone conformation by two silicon atoms was achieved and its structure confirmed by X-ray diffraction on a single crystal. Koiland 2, a concave building block possessing two calix-type pre-organised cavities disposed in a divergent fashion as well as ethyl groups as potential connector moieties, affords either a discrete exo-binuclear inclusion complex in the solid state in the presence of p-xylene acting as a stopper or infinite 1-D or 2-D self-inclusion networks or koilates, mainly based on van der Waals interactions and resulting from the inclusion processes taking place between concave and convex moieties of consecutive koilands.
