Abstract
The mixed-metal oxo clusters LnTi(4)O(3)(OiPr)(2)(OMc)(11) (Ln = La, Ce; OMc = methacrylate), Ln(2)Ti(6)O(6)(OMc)(18)(HOiPr) (Ln = La, Ce, Nd, Sm) and Ln(2)Ti(4)O(4)(OMc)(14)(HOMc)(2) (Ln = Sm, Eu, Gd, Ho) have been synthesized from titanium isopropoxide, the corresponding lanthanide acetate and methacrylic acid. The type of cluster obtained strongly depends on the size of the lanthanide ion.
