title: Phosphonate-substituted zirconium oxo clusters.
abstract: The phosphonate-substituted zirconium oxo clusters Zr6O2(OBu)12(O3PPh)4and Zr7O2(OiPr)12(O3PCH2CH2CH2Br)6, with octahedrally coordinated Zr atoms, were synthesized by reaction of zirconium alkoxides with phosphonic acid bis(trimethylsilyl) esters. The basic structural motif are Zr3O(µ2-OR)3(OR)3units which are connected in different ways.
