Self‐assembly of transition metal ions with different N‐donor ligands and 3,3′‐azodibenzoic acid (3,3′‐H 2 ADB) yielded five novel metal‐organic frameworks. All the 3,3′‐ADB 2– anions got oxidized into 3,3′‐AO 2 DB 2– and 3,3′‐AODB 2– under solvothermal conditions. Compound 1 has a 3D 6‐connected pcu architecture based on [Mn 3 (COO) 6 ] SBU. Compound 2 exhibits 3D threefold interpenetrating framework based on paddlewheel [Mn 2 (COO) 4 ] SBU with 4 12 6 3 topological configuration. Compound 3 bears zigzag double chains, which are then connected by π–π stacking interactions into 2D porous structure. Compound 4 features 2D network with self‐penetrating feature. Compound 5 exhibits a fivefold interpenetrating architecture with dia type. Magnetic measurements show that 1 , 2 and 5 exhibit antiferromagnetic behavior. In addition, compound 3 displays significant adsorption towards methylene blue in aqueous solution. Thermogravimetric analyses for 1–5 and the luminescence properties of 3 and 4 have also been investigated.
