Under hydrothermal condition, the reaction of 2,4‐dichlorophenoxyacetic acid (2,4‐ DH ) and 1,3‐bis(4‐pyridyl)propane with MnCl 2 · 2H 2 O gave a novel metal‐organic framework ( MOF ), [Mn(2,4‐D) 2 ( H 2 O ) 2 ] n ( 1 ). This complex was characterized by IR , elemental analysis, powder X‐ray diffraction, and thermogravimetry analysis. X‐Ray single‐crystal diffraction shows that the Mn( II ) ions are bidendate bridged by carboxyl groups in the syn–anti mode, giving a two‐dimensional ( 2D ) network. Temperature‐dependent magnetic studies reveal that there are weak antiferromagnetic exchange interactions between the Mn( II ) ions transmitted by carboxyl groups.
