Synthesis, characterization, and degradation investigation of a novel (1D + 2D) coordination polymer

Abstract

A new compound, {[Co(TPA)(PYIM)₂(H₂O)₂](MI)₄}_n(1)(H₂TPA = terephthalic acid, PYIM = 2-(3-pyridine) benzimidazole, MI = 2-lmidazolidone) has been urothermal synthesized and structurally characterized by elemental analysis, IR Spectra, the Powder Diffraction and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis reveals that the (1 D)+(2D hydrogen bonds) pillar the compound 1 into an open 3 D supramolecular framework with a pore along the b axis (approximate dimensions 4.5 × 15 Ų), which is occupied by free MI molecules. In addition, the catalytic-degradation capacity of compound 1 for methylene blue (MB) was investigated.
