The Cp derivative 4 possesses a trigonal-bipyramidal Ru4W core in which the W atom is located at an equatorial position and the hydride lies on a Wru 2triangular face. In contrast, the Cp* derivatives 5 and 6 adopt an edge-bridged tetrahedral geometry with a tentacle Cp*M fragment bridging a Ru-Ru edge, on which the novel μ4-η2-CO ligand is associated with the local butterfly Ru3M array (M = Mo, W). The solution dynamics of these three cluster compounds are discussed.8enjournal article
