Two tosylated isophthalic ligands, namely, 5-tosyloxy-isophthalic acid (H2toip) and 5-tosylamino-isophthalic acid (H2taip) were synthesized. Self-assembly of CuII ions with H2toip and H2taip ligands under different reaction conditions (temperature, solvents, and auxiliary ligands) gave rise to three coordination polymers formulated as [Cu(toip)(py)2]n (1), [Cu 6(toip)6(H2O)6]n· 8n(H2O) (2), and [Cu6(taip)6(py) 4(dmf)2]n·n[(dmf)6(MeOH) 2(H2O)2] (3) (py = pyridine, dmf = dimethylformamide). Compound 1 is a one-dimensional (1D) coordination polymeric chain. Compounds 2 and 3 are two-dimensional (2D) coordination networks featuring very similar Kagome lattices based on the interconnection of paddle-wheel [Cu2(COO)4] secondary building units (SBUs) and toip2-/taip2- ligands. However, the arrangement of adjacent Kagome lattices in 2 and 3 are distinct, making them crystallize in different space groups and thereby have different crystal structures. Copyright
