Synthesis, Structure, and Thermal Stability of Supramolecular Polymers with 1D Chain : [M(BPP)‎2(TBTA)‎(H2O)‎2]n[M=Mn(1)‎,Co(2)‎]

الملخص EN

Two supramolecular polymers [M(BPP)2(TBTA)(H2O)2]n[M=Mn(1),Co(2)] 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.
