摘要
An iron(II) complex with tris(pyrazol-1-yl)methane (HC(Pz)(3)) of the composition [Fe(HC(Pz)(3)))(2)]center dot[Eu(dipic)(2)(Hdipic)]center dot 2H(2)O, 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 chi(T) in the temperature range 80-470 K reveals that the polycrystalline phase of the compound undergoes spin-crossover (1) D (1) a double dagger" D-5 cent(2). The transition is accompanied by thermochromism (color change pink a double dagger" white).
