Abstract:
Reaction of the rigid ligand 2,4,5,6‐tetrachloro‐1,3‐benzenedicarboxylic acid (1,3‐H 2 BDC‐Cl 4 ) with copper(II) nitrate in different solvent systems afforded two new complexes {[Cu(1,3‐BDC‐Cl 4 )(DMF)] (H 2 O)} n ( 1 ) and {[Cu(1,3‐BDC‐Cl 4 )(H 2 O) 3 ] (dioxane) · (H 2 O)} 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 P 2 1 / 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‐Cl 4 , 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‐H 2 O] n chains and 1,3‐BDC‐Cl 4 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.
