Abstract
A new neutral ligand 1,1′-(1,4-butanediyl)bis(imidazole-2-phenyl) (bbip) and six coordination polymers, namely [Zn(o-bdc)(bbip)]·H2O (1), [Zn(m-bdc)(bbip)]·H2O (2), [Cd(m-bdc)(bbip)] (3), [Zn(OH–bdc)(bbip)] (4), [Cd(OH–bdc)(bbip)] (5) and [Zn(fum)(bbip)]·H2O (6) (where o-H2bdc = 1,2-benzenedicarboxylic acid, m-H2bdc = 1,3-benzenedicarboxylic acid, OH–H2bdc = 5-hyroxyisophthalic acid and H2fum = fumaric acid), are described. Compound 1 shows a one-dimensional double-stranded chain structure. Compounds 2 and 4 possess 2D polymeric layers, and the layers are connected through van der Waals forces and hydrogen bonds into 3D supramolecular structures, respectively. Compounds 3, 5 and 6 exhibit 3-fold interpenetrating diamondoid networks. The luminescent properties for these compounds in the solid state are discussed.
