Abstract
An unsymmetrical koiland 5 based on the double fusion of two different calix[4]arenes by two silicon atoms has been prepared and structurally characterised. Using p-xylene and phenylpropyne as symmetrical unsymmetrical connectors, respectively, directional 1-D inclusion networks have been obtained and structurally characterised by X-ray diffraction methods on single crystals. In both cases, the 1-D networks were packed in a parallel fashion. However, the linear arrays were oriented in opposite directions, thus leading to non-directional systems.
