Abstract

Two supramolecular polymers have been constructed from 2,3,5,6-tetrabromoterephthalic acid (H2TBTA) and 1,3-bis(4-pyridyl)propane (BPP) ligands in water-methanol dissolvant. Single-crystal X-ray and powder diffraction, IR spectroscopy, thermogravimetric analysis, and elemental analysis were employed to characterize all samples. Both of the complex compounds 1 and 2 belong to triclinic crystal system with P-1 space group. The crystal structures analysis indicates that the metal atom coordinated by two carboxylate groups from different TBTA ligands, two BPP, molecules and two H2O molecules formed a slightly distorted octahedral configuration. The compounds of 1 and 2 are 1D chains made with TBTA spacers, BPP molecules, and H2O molecules.
