Abstract: The complex [(eta(6)-C6Me6)Ru(mu-Cl)Cl](2) 1 react with sodium salts of beta-diketonato ligands in methanol to afford the oxygen bonded neutral complexes of the type [(eta(6)-C6Me6)Ru(kappa(2)-O,O'-(RCOCHCOR2)-C-1)Cl] {R-1, R-2 = CH3 (2), CH3, C6H5 (3), C6H5 (4), OCH3 (5), OC2H5 (6). Complex 4 with AgBF4 yields the gamma-carbon bonded ruthenium dimeric complex 7. Complex 4 also reacts with tertiary phosphines and bridging ligands to yield complexes of the type [(eta(6)-C6Me6)Ru(kappa(2)-O,O'-C6H5COCHCOC6H5)(L)](+) (L = PPh3 (8), PMe2Ph (9)) and [{eta(6)-C6Me6)Ru(kappa(2)-O,O'-C6H5COCHCOC6H5)}(2)(mu-L)] L = 4,4'-bipyridine (4,4'-bipy) (11), 1,4-dicyanobenzene (DCB) (12) and pyrazine (Pz) (13). Complexes 2-4 react with sodium azide to yield neutral complexes [(eta(6)-C6Me6)Ru(kappa(2)-O,O'- (RCOCHCOR2)-C-1)N-3] {R-1, R-2 = CH3 (10a), CH3, C6H5 (10b), C6H5 (10c). All these complexes were characterized by FT-IR and FT-NMR spectroscopy as well as analytical data. The molecular structures of complexes [(eta(6)-C6Me6)Ru(kappa(2)-O,O'CH3COCHCOC6H5)Cl] (3) and [(eta(6)-C6Me6)Ru(kappa(2)-O,O'-C6H5COCHCOC6H5] (4) were established by single crystal X-ray diffraction studies. The complex 3 crystallizes in the triclinic space group, P1 [a = 7.9517(4), b = 9.0582(4) and c = 14.2373(8) angstrom, alpha = 88,442(3)degrees, beta = 76.6.8(3)degrees and gamma = 81.715(3)degrees. V = 987.17(9), angstrom(3), Z = 2]. Complex 4 crystallizes in the monoclinic space group, P2(1)/c [a = 7.5894(8), b = 20.708(2) and c = 29.208(3) angstrom,beta = 92.059(3)degrees V = 4587.5(9) angstrom(3) Z = 8]. (c) 2004
