An ultra‐microporous CoHAtzOx (HAtz = aminotriazole, Ox = oxalate) metal–organic framework with a 3D framework showing guest‐dependent reversible structural transformations was studied. The flexibility was found to arise from buckling of the rigid Co–Ox and Co–HAtz chains, which yields a desolvated structure with a 78 % lower void volume and significantly lower CO 2 capacity.
