Crystal structure and physical properties of a ruthenium(II) bipyridine dimethylsulfoxide complex

摘要: The complex [Ru(bpy)2(DMSO)C1]PF6, where bpy is 2,2′-bipyridine and DMSO dimethylsulfoxide, crystallizes in the triclinic space group P1¯ (#2) with a = 8.873 (2), b 12.805 (4), c 12.864 (4) A, α 97.76(3), β 106.45(2), γ 107.88(2); Z 2, d calc 1.75 mg/m3. coordination geometry that of distorted octahedron cis −RuN4SCl arrangement coordinating atoms. four Ru—N distances to ligands are 2.082(5), 2.092(4), 2.044(4), 2.078(5) A. Ru—Cl distance 2.421(2) A Ru—S 2.260(1) bond trans Cl shortest; S longest. oxidized reduced reversibly at 1.13 −1.37 V vs. SSCE, respectively.
