摘要:
The reactions of [(eta(5)-Cp*)Ru(PPh3)(2)(CH3CN)]X (1) and [(eta(5)-indenyl)Ru(PPh3)(2)(CH3CN)]X (2) (eta(5)-CP* = eta(5)-C5Me5; eta(5)-indenyl = eta(5) -C9H7; X = BF4 or PF6) with 2,2'-bipyridine (bipy.) and 1,10-phenanthroline (phen.) in benzene or toluene yielded complexes of the type [(eta(5)-Cp*)Ru(PPh3)(L-2)]X where L-2 = bipy, X = BF4 (3) and L-2 = phen, X = PF6 (4); [(eta(5)-indenyl)Ru(PPh3)(2)(L-2)]X where L2 = bipy, X = PF6 (5) and L2 = phen, X = PF6 (6). Complex 6 has been established by single crystal X-ray diffraction analysis. Complex 6 crystallizes in the monoclinic space group P 21/c, with a = 14.6020 (12), b = 12.7100 (17) and c = 18.981 (2) Angstrom, beta = 98.982 (9)degrees, V = 3479.5 (7) Angstrom(3) and Z = 4. These complexes can also be prepared from reactions Of [(eta(5)- Cp*)Ru(PPh3)(2)Cl] (7) and [(eta(5)-indenyl)Ru(PPh3)(2)Cl] (8) with the corresponding ligands in the presence of NH4PF6 or NH4BF4 in toluene. All the complexes were characterized by spectral and analytical data. (C) 2002 Elsevier Science Ltd. All rights reserved.
