摘要:
A tetraruthenium carbonyl cluster, (mu(3):eta(1):eta(3):eta(5)-3,4,5-trihydroacenaphthylenyl)Ru4H(CO)(9) (3), was synthesized from (mu(3):eta(1):eta(5)-dihydroacenaphthylene)Ru3H2(CO)(12) (2) in chloroform. The molecular structure showed the trihydroacenaphthylenyl ligand to be a rare example of triply bridging nine electron donor ligands, being bound to three ruthenium atoms by the face-capping mode. One ruthenium atom was bonded by the pi-cyclopentadienyl coordination mode, whereas the latter two were bound to four carbons in the six-membered ring by the eta(1):eta(3)-bonding mode.
