Abstract: The reactions of 4-hydroxyphthalic acid (H2hpc) and 1,2-bi (4-pyridyl) ethane (bpa) with Zn/Cd (II) salts yield two novel 2D layer structures. [Zn(hpc)(bpa)]n (1) consists of hpc anion-bridged mononuclear ZnII chains that are joined further by flexible trans-bpa ligands into a 2D layer. Different from complex (1), the 2D layer structure of [Cd(hpc)(bpa)(H2O)]n (2) features hpc-bridged binuclear cadmium(II) motifs cross-linked by flexible trans-bpa ligands along different directions. Photoluminescence measurements of (1) and (2) in the solid state at room temperature show that there is a slight difference in their fluorescent properties probably due to the different metal ions and coordination environments, which allows a case study on the structure-property correlation.
