| Abstract: | The thermal reaction of Ru3(CO)12 ( 1 ) with salicylic acid, in the presence of triphenylphosphine, pyridine, or dimethylsulfoxide, afforded the dinuclear complexes Ru2(CO)4(μ‐O2CC6H4OH)2L2 ( 2 ) L = PPh3 ( 2a ). C5H5N ( 2b ); (CH3)2SO ( 2c )]. Complex 2b was further reacted with the aromatic dimmines 2,2′‐dipyridine or 1,10‐phenanthroline to give the cationic diruthenium complexes Ru2(CO)2(μ‐CO)2(μ‐O2CC6H4OH)(N∩N)2]+ ( 3 ) (N∩N) = 2,2′‐dipyridine ( 3a ); 1,10‐phenanthroline ( 3b )], which were isolated as their tetraphenylborate salts. All five novel complexes were characterized spectroscopically and analytically. For 2a – 2b and 3a – 3b , single‐crystal X‐ray diffraction studies were also carried out. |
