Design and structural analysis of interpenetrated 3-D co-ordination networks formed by self-assembly using tetrapyridinocyclophane and silver cations

A [1,1,1,1]metacyclophane blocked in the 1,3-alternate conformation and bea ring four pyridine units leads, under self-assembly conditions in the cryst alline phase, to the formation of a fourfold interpenetrated 3-D co-ordinat ion network in the presence of silver cations; the 3-D net is generated thr ough the bridging by linearly co-ordinated silver cations of consecutive te ctons presenting a pseudo-tetrahedral arrangement of four co-ordination sit es.
