Abstract: 
Reaction of Y₅O(OiPr)₁₃ ("yttrium iso-propoxide") with one molar equivalent of isopropyl acetoacetate (iprac) per Y resulted in the formation of Y₉O(OH)₉(OiPr)₈(iprac)₈, a rare example of an yttrium alkoxo/hydroxo/oxo cluster. Reaction in a 1:3 molar ratio gave Y₄(OH)₂(iprac)₁₀ and Y₆(OH)₆(iprac)₁₂ instead. A fourth cluster, Y₉O(OH)₉(iprac)₁₆, structurally closely related to Y₉O(OH)₉(OiPr)₈(iprac)₈, was obtained upon recrystallization of Y₄(OH)₂(iprac)₁₀ from CDCₗ₃.
