The ligands (C5Me4R) [R =n-Butyl (1), Benzyl (2), PhMe-2 (3)] reacted with Ru3(CO)12 in refluxing xylene to give corresponding new substituted tetramethylcyclopentadienyl diruthenium metal carbonyl complexes [(η5-C5Me4R)Ru(CO)( μ-CO)]2 [R=n-Butyl (4), Benzyl (5), PhMe-2 (6)], respectively. The three new complexes were characterized by elemental analysis, IR and 1H NMR spectra. The crystal structure of complex 5 was determined by single crystal X-ray diffraction. The X-ray crystal structure of complex 5 confirms the structure with bridging and terminal CO groups. CCDC: 709601. 相似文献
