Abstract Two isomorphic microporous metal–organic frameworks (MOFs), [Co 2 L(H 2 O) 2 ] · 4.5H 2 O ( 1 ) and [Ni 2 L(H 2 O) 2 ] · 3.5H 2 O ( 2 ), were synthesized by the reaction of an aminopolycarboxylate ligand (H 4 L) with Co and Ni hydroxides under hydrothermal conditions. The exquisite assembly of the carboxylate, imino groups, and metal ions resulted in a 1D special nanotube that could be used as a blueprint for the construction of MOFs. By joining the nanotubes with the V‐shaped –CH 2 (C 6 H)(CH 3 ) 3 CH 2 – spacer, a 3D framework with 1D triangular channels was formed. The two isostructural frameworks exhibited stability up to 350 °C. Gas sorption studies for N 2 , H 2 , CO 2 , and CH 4 confirmed their permanent porosity.
