V. Artero et al., (eta(6)-arene)ruthenium oxomolybdenum and oxotungsten clusters. Stereochemical non-rigidity of [{Ru(eta(6)-p-MeC6H4Pri)}(4)Mo4O16] and crystal structure of [{Ru(eta(6)-p-MeC6H4Pri)}(4)W2O10], CHEM COMMUN, (10), 2000, pp. 883-884
According to a multinuclear NMR study, the cluster [{Ru(eta(6)-p-MeC6H4Pri)
}(4)Mo4O16] exists as two isomers, the windmill-like form and the triple-cu
bane form, which are in equilibrium in solution, while the tungsten analogu
e, which has been obtained together with the double-cubane type cluster [{R
u(eta(6)-p-MeC6H4Pri)}(4)W2O10] by reaction of [{Ru(eta(6)-p-MeC6H4Pri)Cl-2
}(2)] with (NBu4n)(2)[WO4] in acetonitrile, only displays the windmill-like
structure.
