Abstract
Two stable supramolecular microporous polymers with double-layer structures, [Co(AIP) (BPY)(0.5) center dot H2O](n)center dot 2nH(2)O (1) and [Ni(AIP)(BPY)(0.5) center dot H2O](n) center dot 2nH(2)O (2), were constructed from AIP (5-aminoisophthalate) and BPY (4,4'-bipyridine) under hydrothermal conditions. Both of them exhibit rarely reported (3,4)-connected (6(3))(6(5)8) topology and interesting water-induced reversible transformation properties that are confirmed by PXRD studies.
