Abstract
- Four coordination polymers (CPs) based on H 2 tbta ligand, namely, [Zn(tbta) (bmbp)] n (1), {[Cd 0.5 (tbta) (H 2 O)] n ·(Hbia) (H 2 O)} (2), [Cu 1.5 (tbta) (OH) (bi) (H 2 O)] n (3) and [Cd(tbta) (ei) 2 ] n (4) have been synthesized and characterized (H 2 tbta = 2,3,5,6-tetrabromoterephthalic acid, bmbp = 4,4'-dimethyl-2,2'-bipyridine, bia = 1H-benzo[d]imidazol-2-amine, bi = 1H-benzo[d]imidazole, ei = 2-ethyl-1H-imidazole). Single-crystal X-ray diffraction analyses illustrate 1 and 4 exhibit 1D chains, and compound 1 and 4 are hydrogen-bonded into a 2D layer to form a 3D supramolecular structure. Compounds 2 and 3 show 2D layered structures and further expand to 3D supramolecular structures through hydrogen bonds. Structural comparisons indicate that the position of coordination sites and substituent groups plays a crucial role in the control of the final structures. Besides, the photoluminescence properties of compounds 1 , 2 , 4 and UV–vis spectra of 3 have been investigated in the solid state at room temperature. Image 1 • Four CPs based on H 2 tbta ligand were synthesized and structurally characterized. • The auxiliary ligands drastically affect the formation of low-dimensional structures. • The UV–vis spectrum and luminescence properties were studied.
