摘　　要：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.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.
