The crystal structures of many spin crossover solids have intricate architectures consisting of spin-active complexes as well as spin-inactive components, such as counterions and solvent molecules. The latter components undergo temperature induced ordering, in parallel with the spin conversion. This phenomenon has been observed experimentally by X-ray diffraction for compounds with disordered solvent molecules, counterions, and ligands. The structural data illustrating this phenomenon will be shown together with discussion of theoretical approaches mapping various ordering scenarios.
