Abstract

Abstract: Two isomorphic microporous metal–organic frameworks (MOFs), [Co2 L(H2 O)2 ]· 4.5H2 O (1 ) and [Ni2 L(H2 O)2 ]· 3.5H2 O (2 ), were synthesized by the reaction of an aminopolycarboxylate ligand (H4 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 –CH2 (C6 H)(CH3 )3 CH2 – spacer, a 3D framework with 1D triangular channels was formed. The two isostructural frameworks exhibited stability up to 350 °C. Gas sorption studies for N2, H2, CO2, and CH4 confirmed their permanent porosity.
