“…This technique has already been used to detect the existence of metastable states in complexes containing the nitroprusside anion [25,26] and some ruthenium mononitrosyl anionic [27,28] and cationic complexes. [29] With DSC we can determine the amount of energy, which heats the lattice during the thermal decay of metastable states.…”

“…[5] The unique properties of this class were com- [6][7][8] where light irradiation induces a rotation of the NO ligand by 180°in the [Fe(CN) 5 NO] 2-complexes, [9] as illustrated in y. [10][11][12][13] In all these compounds light-induced linkage isomers of the NO ligand can be accessed by a metal-to-NO chargetransfer transition. Hence it can be suggested that any representative potentially shows photorefraction and that it belongs to the class of unconventional photorefractive materials.…”

The ongoing search for new photorefractive materials offering a high photosensitive flexibility is triggered by the limited tuning ability of conventional photorefractive materials, such as electro-optic crystals, photopolymers, or liquid crystals. One of the latest discovered photorefractive materials is Na 2 [Fe(CN) 5 NO] · 2H 2 O, in which metastable linkage isomers of the nitrosyl group can be generated by light irradiation resulting in huge changes of the refractive index up to Dn ∼ 10 -2 .Here we show that this type of photorefraction is a general property arising from the generation of linkage isomers and can thus be found in many compounds containing [ML 5 NO] m± complexes, where M is a transition metal, L a ligand, and m the formal charge of the anion/cation. The benefit of this generality is reflected in the tailoring properties of the photorefractive response such as the spectral sensitivity simply by selecting different representatives of the [ML 5 NO] m± compounds.Conventional photorefractive materials, [1] where the lightinduced modulation of the refractive index is caused by the linear electro-optic effect (Pockels effect), are widely applied in nonlinear optics.[2] They feature reversible photorefractivity without chemical processing allowing for dynamical holography, [3] and the kinetics of hologram formation is described by the well-known Kiev equations. [4] In recent years a second class of reversible photorefractive media for dynamical holography has been established, the unconventional photorefractive materials. Here an optical bistability is at the origin of photorefraction and the kinetics show a characteristic transient behavior.[5] The unique properties of this class were com-

“…Probably only a dynamic change of the new electron density distribution in SI may explain the assumption in Ref. (11) that there exists a distinct correlation between the energy distribution in the phonon the Mö ssbauer parameters of SII. Although, with very close values of the Mö ssbauer parameters the new states spectrum and the decay temperature.…”
