title: Modification of yttrium alkoxides: β-Ketoesterate-substituted yttrium alkoxo/hydroxo/oxo clusters.
abstract: Reaction of Y(5)O(OiPr)(13) ("yttrium iso-propoxide") with one molar equivalent of isopropyl acetoacetate (iprac) per Y resulted in the formation of Y(9)O(OH)(9)(OiPr)(8)(iprac)(8), a rare example of an yttrium alkoxo/hydroxo/oxo cluster. Reaction in a 1:3 molar ratio gave Y(4)(OH)(2)(iprac)(10) and Y(6)(OH)(6)(iprac)(12) instead. A fourth cluster, Y(9)O(OH)(9)(iprac)(16), structurally closely related to Y(9)O(OH)(9)(OiPr)(8)(iprac)(8), was obtained upon recrystallization of Y(4)(OH)(2)(iprac)(10) from CDCl(3).
