摘要: A one-dimensional metal organic oxide of Mn(II), with formula [Mn3(OH)2(Hpdc)2]n (H3pdc = 3,5-pyrazoledicarboxylic acid), was prepared via the hydrothermal method and its structure solved by single-crystal X-ray diffraction. The compound exhibits a three-dimensional framework structure, comprising three crystallographically unique Mn atoms bridged OH ligands (O9 O10) O from Hpdc ligands, forming metal–organic chains. Two kinds magnetic exchange are observed: strong antiferromagnetic intra-chain interaction, arising short distance between Mn(II) centers, ferromagnetic inter-chain due to larger distances shows good photocatalytic activity for decomposition methylene blue in aqueous medium under simulated sunlight.
