In order to explore new coordination frameworks with novel designed 3-nitrophthalic acid and the same N– donor ancillary ligand, a series of novel coordination complexes, namely, [Cd 2 (3-NPA) 2 (TBZ) 2 (H 2 O) 2 ]·2H 2 O (1), [Zn 2 (3-NPA) 2 (TBZ) 2 ] (2), [Zn 2 O(3-NPA)(TBZ)(H 2 O)] n (3), [Co(3-NPA)(TBZ)(H 2 O)] n (4) (3-NPAH 2 = 3- nitrophthalic acid), have been hydrothermally synthesized through the reaction of 3-nitrophthalic acid with divalent transition-metal salts in the presence of N-donor ancillary coligand (TBZ = thiabendazole). As a result of various coordination modes of the versatile 3-NPAH 2 and the coligand TBZ, these complexes exhibit structural diversity. X-ray structure analysis reveals that 1 and 2 are 0D molecular rings, while 3 and 4 are one- dimensional (1D) infinite chain polymers. And the weak O-H…O hydrogen bonds and C-H…O nonclassical hydrogen bonds as well as π-π stacking also play important roles in affecting the final structure where complexes 1, 3 and 4 have 3D supramolecular architectures, while complex 2 has a 2D supramolecular network. Also, IR spectra, fluorescence properties and thermal decomposition process of complexes 1-4 were investigated. KCI Citation Count: 2
