Coordination of C60 to Penta- and Hexaruthenium Cluster Frames

In refluxing chlorobenzene C 60 reacts with Ru 5 C(CO) 15 or with Ru 6 C(CO) 17 to form new complexes, which are isolated following treatment with tertiary phosphines to give the structurally characterized, face-bonded derivatives Ru 5 C(CO) 11 (PPh 3 )(μ 3 -η 2:η 2:η 2 -C 60 ) ( 1 ) and Ru 6 C(CO) 12 (dppm)(μ 3 -η 2:η 2:η 2 -C 60 ) ( 2 ).
