Three new mixed‐ligand coordination polymers of Cu II , namely, [Cu(Fbtx)(L1)(H 2 O)] n ( 1 ), [Cu(Fbtx) 0.5 (HL2)(H 2 O) 2 ] n ( 2 ), and {[Cu(Fbtx) 1.5 (HL3)(H 2 O)] · H 2 O} n ( 3 ) [Fbtx = 2,3,5,6‐tetrafluoro‐1,4‐bis(1,2,4‐triazole‐1‐ylmethyl)benenze, H 2 L1 = terephthalic acid, H 3 L2 = trimesic acid, NaH 2 L3 = 5‐sulfoisophthalic acid monosodium salt], were hydrothermally synthesized and structurally characterized by elemental analysis, IR spectra, and single‐crystal and powder X‐ray diffraction techniques. All the complexes have a two‐dimensional (2D) coordination layer structure. Of these, 1 displays a planar 4 4 ‐ sql structure whereas both 2 and 3 are highly undulated 6 3 ‐ hcb nets. Moreover, their thermal stability and catalytic behaviors in the aerobic oxidation of 4‐methoxybenzyl alcohol were also investigated as well. The results indicate that the benzene dicarboxylate ligands have an effective influence on the structures and catalytic properties of the resulting coordination polymers.
