Abstract Two metal‐organic frameworks, [Co 2 (ABTC)(bimh)(OH)] · 2H 2 O ( 1 ) and [Co 3 (ABTC) 2 (dimb) 4 ] n ( 2 ) [H 3 ABTC = 3,4′,5‐azobenzenetricarboxylic acid, bimh = 1,1′‐(1,4‐hexanediy)bis(imidazole), dimb = 1,4‐bis(1 H ‐imidazol‐1‐yl)benzene], were prepared under solvothermal conditions and structurally characterized. Complex 1 demonstrates a complicated 3D (3,8)‐connected tfz‐d net with (4 3 ) 2 (4 6 .6 17 .8 5 ) topology. The framework of 2 can be classified as a rare 3D (3,6,6)‐connected net with the Schäfli symbol of (4.6 2 ) 2 (4 2 .6 10 .8 3 )(4 4 .6 10 .8), and exhibits an intriguing self‐penetrating motif. Meanwhile, the thermal stabilities and magnetic properties for 1 and 2 were also probed.
