Abstract
The new clusters Zr6O2(OBu)(10)(OMc)(10) and Zr6O2(OMe)(4)(OBu)(2)(OMc)(14) were prepared from Zr(OBu)(4) and methacrylic acid. For the preparation of Zr6O(2)(OMe)(4)(OBu)(2)(OMc)(14), partial exchange of the butoxy groups is necessary. The clusters consist of two Zr-3 subunits that dimerize via alk oxide bridges. The structures are of the same type, except that four termin al butoxy ligands in Zr6O2(OBu)(10)(OMc)(10) are exchanged for chelating me thacrylate ligands in Zr6O2(OMe)(4)(OBu)(2)(OMc)(14).
