Abstract

{Reaction of [(eta-C(5)Me(5))Mo(O)(mu-O)](2) with [(eta-C(5)Me(5))Mo(CO)(2)]2 plus O-2 give (eta-C(5)Me(5))(4)Mo5O11. This cluster contains (eta-C(5)Me(5))Mo(O)(2) attached to a [(eta-C(5)Me(5))Mo(mu-O)](3)(mu(3)-O)(3)Mo(O)(2) unit-by a bridging oxygen atom. The [Mo(mu-O)](3)(mu(3)-O)(3)Mo structure is favored over the alternative adamantane-like [M(4)(mu-O)(6)] structure because of the pi-bonding of the terminal oxygen atoms attached to the apical Mb atom. The [(eta-C(5)Me(5))Mo(mu-O)](3)(mu(3)-O)(3)Mo(O)(2) unit contains four cluster electrons which are associated with the three basal molybdenum atoms. The magnetic moment of (eta-C(5)Me(5))(4)Mo4O11 was 3.16 mu(B) at 291 K, indicating that the cluster core has two unpaired electrons. Crystal data: C40H60Mo5O11, triclinic, P (1) over bar
