The thermal reaction of Ru 3 (CO) 12 ( 1 ) with salicylic acid, in the presence of triphenylphosphine, pyridine, or dimethylsulfoxide, afforded the dinuclear complexes Ru 2 (CO) 4 (μ‐O 2 CC 6 H 4 OH) 2 L 2 ( 2 ) [L = PPh 3 ( 2a ). C 5 H 5 N ( 2b ); (CH 3 ) 2 SO ( 2c )]. Complex 2b was further reacted with the aromatic dimmines 2,2′‐dipyridine or 1,10‐phenanthroline to give the cationic diruthenium complexes [Ru 2 (CO) 2 (μ‐CO) 2 (μ‐O 2 CC 6 H 4 OH)(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.
