| Abstract: | Two novel metal‐organic coordination polymers, [Mn2(dpa)2(4,4′‐bipy)2(H2O)2]n ( 1 ) and [Mn(Hdpa)2(bpe)(H2O)2]n ( 2 ) (H2dpa = diphenic acid, 4,4′‐bipy = 4,4′‐dipyridine, bpe = 1,2‐bis(4‐pyridyl)ethene), have been hydrothermally synthesized. Single crystal X‐ray diffraction analyses reveal the two‐dimensional and three‐dimensional structures for complexes 1 and 2 , respectively. In 1 , the dpa ligands link metal ions with different modes into one‐dimensional chains, and the 4,4′‐bipy terminally coordinate to the metal ions extending the chains into a layer. Whereas in 2 , the flexible bpe ligands link the structure motifs into chains, and the hydrogen bonding interactions between the chains lead to the formation of cavity structure. |
