Abstract

Illuminating phase changes: Absorption of X-ray photons induces reversible internal charge-transfer processes in the mixed-valence Mn/Fe cyanide Rb 0.7MnII1.15[FeIII(CN) 6]·2 H2O over a broad temperature range. Both continuous and abrupt phase transformations can be triggered (see scheme; HS = high spin, LS = low spin) and because the X-rays simultaneously probe the structural properties of the material, the resulting phase diagram can be elucidated in detail. (Graph presented).
