The reaction of 1,4-bis((1H-imidazoyl-1-yl)methyl)benzene (BIB) and 5-sulfoisophthalic acid (SPA) in a 1:1:1 ratio with zinc(II) ions in water produced a supramolecular cage-like structure of the composition {[Zn(2)BIB(1.5)SPA(OH)(H2O)]center dot 1.75H(2)O}(n). The structure as determined by X-ray crystallography contains two zinc(II) ions; one zinc(II) is four coordinate and approximately tetrahedral, whereas the second zinc(II) is five coordinate and based on a trigonal bipyramid. The two zinc(II) ions are connected by a mu(2)-hydroxyl unit and a mu(2)-carboxylate unit. Two of the central di-zinc(II) motifs are coupled together by the bridging 5-sulfoisophthalate subunit and this feature extends along the a-axis. The 1,4-bis((1H-imidazoyl-1-yl)methyl)benzene act like pillars to connect the rows of zinc(II) ions as viewed down the c-axis. The cavity formed supports inclusion of water molecules and the water channel extends in one dimension through the structure. The water molecules can be removed on heating to T = 373 K, and N-2-uptake adsorption studies reveal the pore volume is 1.8 x 10(-2) cm(3) g(-1) with a total BET surface area of 51.2 m(2) g(-1).
