Two coordination polymers, [Ag 2 (pydca)(bbbi) 2 ] n ( 1 ) and [Co 2 (pydca) 2 (bbbi) 3 ] n · n H 2 O ( 2 ) [pydca = pyridine‐2, 6‐dicarboxylate, bbbi = 1, 1′‐(1, 4‐butylene)bis‐1H‐benzimidazole)] were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, TG, PXRD, and single‐crystal X‐ray diffraction. Compound 1 features a one‐dimensional helical chain structure bridged by bbbi ligand, and further assembled into a 2D supramolecular architecture through three kinds of intermolecular π–π stacking interactions. Compound 2 displays an undulated 2D (6, 3) layer structure, in which each [Co(pydca)] unit is connected by three bbbi bridge ligands. Moreover, 1 and 2 have a remarkable activity for degradation of methyl orange in a photo‐assisted Fenton‐like process.
