title: Constructing robust channel structures by packing metallacalixarenes: reversible single-crystal-to-single-crystal dehydration.
abstract: The self-assembly process involving the dianion of trimesic acid (Htrim(2-)) and {Cu(tmen)}(2+) templating cations (tmen = N,N,N',N'-tetramethylethylenediamine) affords a new metallacalixarene, [Cu(4)(tmen)(4)(Htrim)(4)] x n H(2)O. The packing of the cyclic molecules in the crystal generates channels that are filled by water molecules. The dehydration-rehydration process of the crystals was found to be reversible.
