Abstract
A novel porous framework [{Cu2(medpt)2Ni(CN)4}(ClO4 )2· 2.5H2O]n 1, [medpt = bis(3-aminopropyl)methylamine] is prepared where all the CN groups of Ni(CN)42− are involved in bridging; this material retains single crystallinity upon removal of water guest molecules and the dehydrated species 2 selectively binds organic molecules.
