DSC,X線,UV-Visスペクトル測定による臭素架橋一次元白金錯体の構造相転移とサーモクロミズム現象の研究

We performed the DSC, X-ray and UV-Vis spectrum measurements on [Pt (en)_2] [PtBr_2 (en)_2] (ClO_4)_4 in which a modification was reported by crystallizing from aqueous solution below room temperature. A metastable phase crystallizing below room temperature showed a different phase transition with thermochromism at ca. 380K to the stable form. The obtained X-ray powder patterns confirmed that the phase transition at 380K was transformation into the stable form.
