By using “pillaring” strategy, a new Co(Ⅱ)-MOF, [Co_2(abtc)(bimb)_2]·2H_2O(1, H_4abtc = 3,3?,5,5?-azobenzenetetracarboxylic acid, bimb = 4,4?-bis(imidazole-1-ylmethyl)biphenyl), has been solvothermally synthesized and structurally characterized. The structural determination revealed that 1 features a 3D pillar-layered framework with(4,8)-connected {4~4.6~2}{4~8.6~(20)} topology based on dinuclear Co(Ⅱ)-SBUs. The magnetic investigation shows that the dominant antiferromagnetic coupling is observed in compound 1.
