Aluminium-based cationic metal–organic frameworks remain rare, yet offer opportunities for unusual framework structures and material properties. Here, a robust ultra-microporous cationic metal–organic framework based on aluminium building units and flexible tetracarboxylic acid linkers is reported, and three-dimensional electron diffraction combined with high-resolution powder X-ray diffraction show that the material comprises an ordered defective cationic framework with narrow quasi-1D channels.
