From: A spin-crossover framework endowed with pore-adjustable behavior by slow structural dynamics

a Framework breathing induced by the hinging motion of organic ligands around the metal nodes. b Gate-opening/closing induced by sub-lattice displacive motion. c Framework breathing associated with a pore rearrangement induced by a non-uniform molecular reorientation.
