Abstract
The complex of (CH3Cp)2Yb . DME (DME = dimethoxyethane) has been synth esized by the reduction with metallic sodium of the corresponding chlo ride (CH3CP)2YbCl. (CH3CP)2Yb . DME crystallized from DME in the monoc linic space group Cm, with cell constants a = 11.068(3), b = 12.338(4) , c = 12.479(4) angstrom; beta = 100.51(2)-degrees, V = 1675(l) angstr om3, and D0 = 1.66 g/cm3 for Z = 4. Least-squares refinement of 1420 u nique observed reflections led to final R of 0.0487. This complex can be used as a catalyst for the polymerization of methyl methacrylate (M MA).
