Abstract

By introducing a bis-pyrazole-bis-amide ligand, ,'-bis(1-pyrazole-4-carboxamide)-1,4-benzene (L), two molybdate-based metal-organic complexes containing {M(MoO)} (M = Co, Zn), [CoL(MoO)]·HO (1), [ZnL(MoO)]·HO (2), have been prepared under hydrothermal/solvothermal conditions. X-ray diffraction analyses reveal that both 1 and 2 are isostructural. An interesting structural feature is that a kind of {M(MoO)} chain could be found in 1 and 2, although different raw materials [MoO] and [PMoO] anions were utilized. Then these chains are further linked by L ligands into a two dimensional (2D) structure. The title complexes represent the first examples containing {MoO} units and pyrazole-/or amide-derivative ligands. Complexes 1 and 2 exhibit distinct performances due to different metal centers, with 2 acting as a fluorescent sensor for Fe, MnO , CrO and CrO , but 1 being a better photocatalyst towards degradation of cationic dyes methylene blue (MB) and neutral red (NR).

摘要

通过引入双吡唑双酰胺配体1,4 - 双（1 - 吡唑 - 4 - 甲酰胺基）苯（L），在水热/溶剂热条件下制备了两种含{M(MoO)} （M = Co，Zn）的钼酸盐基金属有机配合物，[CoL(MoO)]·HO（1），[ZnL(MoO)]·HO（2）。X射线衍射分析表明1和2具有同构结构。一个有趣的结构特征是，尽管使用了不同的原料[MoO]和[PMoO]阴离子，但在1和2中都能发现一种{M(MoO)} 链。然后这些链通过L配体进一步连接成二维（2D）结构。标题配合物是包含{MoO}单元和吡唑 - /或酰胺 - 衍生物配体的首个实例。由于金属中心不同，配合物1和2表现出不同的性能，2作为Fe、MnO 、CrO 和CrO 的荧光传感器，而1对阳离子染料亚甲基蓝（MB）和中性红（NR）的降解是更好的光催化剂。
