Abstract
The dinuclear ruthenium complexes Ru 2(CO) 4(OOCC 5H 4FeC 5H 5) 2L 2 (L = NC 5H 5: 1, L = PPh 3: 2) have been synthesized from Ru 3(CO) 12, ferrocene carboxylic acid and pyridine or triphenylphosphine, respectively. The single-crystal X-ray structure analysis reveals for 1 and 2 a Ru 2(CO) 4 sawhorse backbone with the two ferrocenyl substituents of the two carboxylato bridges being endo/ exo with respect to each other in the solid state. With the new pyridine derivative NC 5H 4OOCC 5H 4FeC 5H 5 (4-ferrocenoyl pyridine) ( 3) as axial ligand, the complex Ru 2(CO) 4(OOCC 5H 4FeC 5H 5) 2(NC 5H 4OOCC 5H 4FeC 5H 5) 2 ( 4) was obtained, the single crystal X-ray structure analysis showing an exo/ exo orientation of the two carboxylato bridges in the solid state. The endo/ endo orientation is found in the solid-state structure of Ru 2(CO) 4(HNOCC 5H 4FeC 5H 5) 2(PPh 3) 2 ( 5), the two OCNH bridges being transoïd with respect to each other; this complex is accessible from Ru 3(CO) 12, ferrocenamide and triphenylphosphine.
