Conversion of methacrylate into 2-hydroxy-2-methylpropionate ligands in the coordination sphere of a Ag-Zr oxo cluster

Reaction of Zr((OBu)-Bu-n)(4) and silver acetate with methacrylic acid afforded a mixed-metal cluster with a Ag2Zr8O6 core and both methacrylate and 2-hydroxy-2-methylpropionate ligands.
