Abstract
The three new [2,2] paracyclophane clusters Ru(3)(CO)9(mu3-eta2:eta2:eta2-C16H16) (1), Ru6C(CO)11(mu3-eta2:eta2:eta2-C16H16)(eta6C16H16) (3), and Ru6(C)(CO)12(mu3-eta2:eta2:eta2-C16H16)-(mu2-eta2:eta2-C6H8) (4) have been prepared and characterized spectroscopically. The structures of compounds 3 and 4 have also been analyzed by X-ray diffraction methods. A comparison of the face-capping ligand in these species, together with the known complex Ru6C(CO)14(mu3-eta2:eta2: eta2-C16H16) (2) leads to the observation that the [2.2]-paracyclophane ring bonds to the triruthenium face in a range of differing orientations, from near-staggered to near-eclipsed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
