In molecular spin-crossover materials, the spin-state switching is strongly coupled with changes in the structural degrees of freedom, which play a central role in the alteration of functions and mechanisms of transformation from the molecular scale (bond lengths) to the material scale (volume). This article reviews various techniques currently used, ranging from microscopy to diffraction, to study the structural aspects related to spin crossover at different physical scales. Some of the most important recent advances concern the resolution of complex crystal structures, the determination of microstructures, the study of phase coexistence, temporal studies ranging from second to femtosecond, and the description of multistep transition involving intricate ordering of molecules in different electronic states.


Dans les matériaux moléculaires à conversion de spin, la modification de l'état de spin est fortement couplée aux changements des degrés de liberté structuraux, qui jouent un rôle central dans l'altération des propriétés et dans les mécanismes de transformation, de l'échelle de la molécule (longueur de liaison) à l'échelle du matériau (volume). Cet article passe en revue différentes techniques utilisées actuellement, allant de la microscopie à la diffraction, pour étudier les aspects structuraux fondamentaux liés au changement d'état de spin aux différentes échelles physiques. Les avancées récentes les plus marquantes concernent la résolution de structures cristallines complexes, la détermination des microstructures, l'étude de la coexistence de phases, les études temporelles allant de la seconde à la femtoseconde et la description de transition multi-étapes impliquant des mises en ordre complexes de molécules dans différents états électroniques.
