The reactions of cobalt acetates with tetrachloroterephthalic acid (H 2BDC-Cl4) in different solvents gave two polymeric and one mononuclear CoII complexes. X-ray single-crystal structural determination revealed that the ligand BDC-Cl4 displays a reliable bridging tecton to construct diverse supramolecular architectures through, coordinative bonds or secondary hydrogen-bonding interactions. The complexes [Co(BDC-Cl4)(DMF)2(EtOH)2]n (1) and {[Co(BDC-Cl4)(DMF)2(MeOH)2]·2DMF} n (2) demonstrate a one-dimensional (ID) coordination, motif with infinite CoII-tetrachloroterephthalate chains, which are tuned by different binding solvent systems of DMF/ethanol (EtOH) and DMF/methanol (MeOH). [CO(DMF)2(H2O)4KBDC-Cl4) (3) represents a two-dimensional (2D) metallosupramolecular network by hydrogen-bonded bridging between the aqua ligand of the mononuclear complex with the uncoordinated BDC-Cl4 solvates. The spectroscopic, thermal, and fluorescent properties of 1-3 were also investigated.
