Synthesis and characterization of bimetallic ruthenium complexes connected through linear (CH)14 chain

Treatment of RuHCl(CO)(PPh3)3 with (3E,5E,7E,9E,11E)-HCC–(CHCH)5- CCH produces [RuCl(CO)(PPh3)2]2[μ-(CHCH)7]. The later complex reacts with PMe3 to give [RuCl(CO)(PMe3)3]2[μ-(CHCH)7], the structure of which has been confirmed by X-ray diffraction. The through-space distance from one Ru to the other is 19.88 Å.

The longest (CH)x-bridged bimetallic complex [RuCl(CO)(PMe3)3]2[μ-(CHCH)7] has been synthesized and characterized. The bimetallic complex shows good electronic communication between two metals and good stability.Figure optionsDownload as PowerPoint slide
