一系列双核钌配合物[RuCl（CO）（PMe 3）3]2（μ-CH <$CH−Ar−CH <$CH）（Ar = C6H2（OR）2- 2，5; R = CH 3（4a）、nC4 H9（4 b）、nC6 H13（4c）、nC8 H17（4d）、nC10 H21（4 e）、nC12 H25（4f）、nC14 H29（4g））、[RuCl（CO）（PMe3）3]2合成了（μ-CH <$CH−Ar− <$− CH <$CH）（Ar = C6H2（R）2- 2，5; R = OCH 3（10a），OnC 8H 17（10b），H（10c））和[RuCl（CO）（PMe3）3]2（μ-CH <$CH−Ar − <$−Ar− <$− CH <$CH）（Ar = C6H2（R）2- 2，5; R = OCH 3（13a），OnC 8H 17（13b），H（13c））.这些配合物已通过元素分析，核磁共振，紫外/维斯分光光度法进行了表征。4 b和4d的结构已通过X射线晶体学测定。电化学研究表明，长的碳链连接到配合物的桥促进混合价钌配合物的稳定性。
A series of binuclear ruthenium complexes [RuCl(CO)(PMe3)3]2(μ-CH═CH−Ar−CH═CH) (Ar = C6H2(OR)2-2,5; R = CH3 (4a), nC4H9 (4b), nC6H13 (4c), nC8H17 (4d), nC10H21 (4e), nC12H25 (4f), nC14H29 (4g)), [RuCl(CO)(PMe3)3]2(μ-CH═CH−Ar−≡−Ar−CH═CH) (Ar = C6H2(R)2-2,5; R = OCH3 (10a), OnC8H17 (10b), H (10c)), and [RuCl(CO)(PMe3)3]2(μ-CH═CH−Ar−≡−Ar−≡−Ar−CH═CH) (Ar = C6H2(R)2-2,5; R = OCH3 (13a), OnC8H17 (13b), H (13c)) have been synthesized. These complexes have been characterized by elemental analysis, NMR, and UV/vis spectrophotometry. The structures of 4b and 4d have been determined by X-ray crystallography. Electrochemical studies have shown that long carbon chains attached to the bridges of the complexes facilitate the stability of mixed-valence bimetallic ruthenium complexes.
