To explore the possibility of obtaining the metal‐organic frameworks (MOFs) bearing the 2‐bromo‐1,4‐benzenedicarboxylate ligand, one new Mn(II) and one Co(II) coordination polymers, [Mn(HL) 2 (bipy) 2 ·2H 2 O]·bipy ( 1 ) and [Co(L)(bpe)] ( 2 ) (bipy=4,4′‐bipyridine; bpe=1,2‐bis(4‐pyridyl)ethene) were synthesized and characterized by elemental analysis and X‐ray diffraction analysis. Compounds 1 exhibits one‐dimensional coordination chains, which are further connected to form two dimensional supramolecular networks through hydrogen bonding interactions. Compound 2 presents a two‐fold interpenetrating two‐dimensional layer structure. The 2‐bromo‐1,4‐benzenedicarboxylate anion exhibits different coordination modes in the two complexes.
