different N‐donor ligands and 3,3′‐azodibenzoic acid (3,3′‐H2ADB) yielded five novel metal‐organic frameworks. All the 3,3′‐ADB2– anions got oxidized into 3,3′‐AO2DB2– and 3,3′‐AODB2– under solvothermal conditions. Compound 1 has a 3D 6‐connected pcu architecture based on [Mn3(COO)6] SBU. Compound 2 exhibits 3D threefold interpenetrating framework based on paddlewheel [Mn2(COO)4] SBU with 41263 topological
具有不同N-给体配体和3,3'-偶氮二苯甲酸(3,3'-H 2 ADB)的过渡金属离子的自组装产生了五个新颖的金属有机骨架。在溶剂热条件下,所有3,3'-ADB 2–阴离子均被氧化为3,3'-AO 2 DB 2–和3,3'-AODB 2–。化合物1具有基于[Mn 3(COO)6 ] SBU的3D 6连接的pcu体系结构。化合物2表现出基于具有4 12 6 3拓扑构型的桨轮[Mn 2(COO)4 ] SBU的3D三重互穿框架。化合物3个熊之字形双链,然后通过π-π堆积相互作用连接成2D多孔结构。化合物4具有具有自动穿透功能的2D网络。化合物5显示出dia类型的五重互穿结构。磁性测量表明,1,2和5表现出反铁磁行为。另外,化合物3在水溶液中显示出对亚甲蓝的显着吸附。还对1–5的热重分析以及3和4的发光性质进行了研究。
