|Section2= |Section3= |Section7= |Section8= }} Tris(bipyridine)ruthenium(II) chloride is the coordination compound with the formula ()Cl2. This red crystalline salt is obtained as the hexahydrate, although all of the properties of interest are in the cation ()2+, which has received much attention because of its distinctive optical properties. The chlorides can be replaced with other anions, such as PF6−. ==Synthesis and structure== This salt is prepared by treating an aqueous solution of ruthenium trichloride with 2,2'-bipyridine. In this conversion, Ru(III) is reduced to Ru(II), and hypophosphorous acid is typically added as a reducing agent.〔Broomhead, J. A.; Young, C. G. "Tris(2,2’-bipyridine)Ruthenium(II) Dichloride Hexahydrate" Inorganic Syntheses, 1990, volume 28, pp. 338-340. 〕 ()2+ is an octahedral coordination complex. The complex is chiral, with D3 symmetry. It has been resolved into its enantiomers, which are kinetically stable. In excited state the molecule loses symmetry and attains C2 symmetry, as the transferred electron doesn't distribute symmetrically to the 3 bipyridyl ligands. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tris(bipyridine)ruthenium(II) chloride」の詳細全文を読む スポンサード リンク
