Structural Rearrangements Induced by Photoexcitation in a RbCoFe Prussian Blue Derivative

Light influence: The Co crystal-field parameter was used as a probe of the photoinduced metastable state of a RbCoFe Prussian blue analogue. From the light-induced change in this parameter, a scheme of the photoinduced structural rearrangement is proposed in which cooperative interactions within the three-dimensional structure impose linear geometry on all Co-NC-Fe entities in the metastable state (see picture).
