Abstract
An iron(II) complex with tris(pyrazol-1-yl)methane (HC(Pz)) of the composition [Fe(HC(Pz)))]·[Eu(dipic)(Hdipic)]·2HO, containing an outer-sphere complex anion, is synthesized. The compound is examined by single crystal and powder X-ray diffraction, UV-Vis and IR spectroscopies, and static magnetic susceptibility. The investigation of the temperature dependence χ( T) in the temperature range 80-470 K reveals that the polycrystalline phase of the compound undergoes spin-crossover А ⇔ Т. The transition is accompanied by thermochromism (color change pink ⇔ white). [ABSTRACT FROM AUTHOR]
