title: Tetranuclear organometallic complexes containing Mo2O4(2+) and allylmolybdenum(II) moieties.
abstract: Refluxing toluene solutions of [Mo(η(3)-allyl)(O(2)CMe)(CO)(2)(pz*H)(2)] (pz*H = pzH, pyrazole, or dmpzH, 3,5-dimethylpyrazole) without exclusion of air, give the tetranuclear complexes [Mo(2)O(2)(O(2)CCH(3))(2){(μ(3)-O)(μ-pz*)Mo(η(3)-allyl)(CO)(2)(pz*H)}(2)], where two chelating acetato ligands and two "Mo(η(3)-allyl)(CO)(2)(pz*H)(μ-pz*)" fragments are bonded to a central Mo(2)O(4)(2+) moiety.
