Self-assembly of two 2D copper(II) coordination networks with tetrachloro-1,3-benzenedicarboxylate: Solvent effects, supramolecular interactions, and luminescence behavior

Reaction of the rigid ligand 2,4,5,6-tetrachloro-1,3-benzenedicarboxylic acid (1,3-H2BDC-Cl4) with copper(II) nitrate in different solvent systems afforded two new complexes {[Cu(1,3-BDC-Cl4)(DMF)] (H2O)}n (1) and {[Cu(1,3-BDC-Cl4)(H 2O)3] (dioxane)·(H2O)}n (2), which were fully characterized by elemental analysis, IR spectroscopy, as well as single crystal and powder X-ray diffiraction techniques. Single-crystal X-ray diffraction reveals that complexes 1 and 2 crystallize in different space groups P21/m and Pbca, respectivly. Compound 1 shows a two-dimensional (2D) (4,6)-connected layered network constructed by the connectivity between one-dimensional (1D) [-Cu-DMF-COO-]n chains and tetrachlorinated backbones of 1,3-BDC-Cl4, which is further assembled to generate a three-dimensional (3D) supramolecular framework through intermolecular O-H...O and O-H...Cl hydrogen-bonding interactions. Compound 2 features a 2D 4-connected sql coordination net formed by 1D [Cu-H2O]n chains and 1,3-BDC-Cl4 spacers, which is further extended into a 3D supramolecular network by multiple O-H...O hydrogen-bonding interactions. The different structural features of the two compounds suggest that the choice of solvent systems should play a key role in the process of assembly. Their thermal and fluorescence properties were also investigated. Copyright
