摘要

The new clusters Zr_6o_2(OBu)_10(OMc)_10 and Zr_6O_2(OMe)_4(OBu)_2(OMc)_14 were prepared from Zr(OBu)_4 and methacrylic acid. For the preparation of Zr_6O_2(OMe)_4(OBu)_2(OMc)_14, partial exchange of the butoxy groups is necessary. The custers consist of two Zr_3 subunits that dimerize via alkoxide bridges. The structures are of the same type, except that four terminal butoxy ligands in Zr_6O_2(OBu)_10(OMc)_10 are exchanged for chelating methacrylate ligands in Zr_6O_2(OMe)_4(OBu)_2(OMc)_14.
