Abstract

Hydrothermal synthesis has afforded a series of zinc-containing coordination polymers incorporating the kinked organodiimine 4,4′-dipyridylamine (dpa) and phenylenediacetate (phda) isomers. {[Zn(1,4-phda)(dpa)]·H2O}∞ (1) manifests a two-dimensional (2D) corrugated layer morphology. While both {[Zn(1,2-phda)(dpa)]·2H2O}∞ (2) and [Zn(1,3-phda)(dpa)]∞ (3) contain three-dimensional 4-fold interpenetrated coordination polymer networks, 2 possesses the SrAl2 structure type (sra, 42638 topology) but the acentric material 3 adopts the diamond structure type (dia, 66 topology). The varying morphologies thus reveal a significant structure-directing effect of the position of the acetate groups during self-assembly of these coordination polymers. Hydrogen-bonding mechanisms imparted by the central amine group of the dpa ligand provide ancillary supramolecular structure-directing effects in all three cases. All three materials undergo blue–violet luminescence upon irradiation with ultraviolet light.
