Mi. Bruce et al., SOME CHEMISTRY OF RU-3(MU-H)(MU(3)-CMECHCME)(CO)(9) - REACTIONS WITH DIPHENYLETHYNE AND CHARACTERIZATION OF A DIGOLD DERIVATIVE, Australian Journal of Chemistry, 50(9), 1997, pp. 875-878
The complex Ru-3(mu(3)-CEtCMeCPhCPh)(CO)(7){Au-2(PPh3)(2)} (3) has bee
n shown by a single-crystal X-ray structure determination to contain a
C4Au2Ru3 cluster with an unusual geometry, consisting of the Au-2 uni
t interacting with a C4Ru3 pentagonal bipyramid. Complex (3) was obtai
ned from [O{Au(PPh3)}(3)][BF4]/[ppn][Co(CO)(4)] and the product (2) ob
tained from C2Ph2 and Ru-3(mu-H)-(mu(3)-CMeCHCMe)(CO)(9), previously a
ssumed to have a CMeCEtCPhCPh ligand.
