摘      要：(2,4 C 7H 11 ) 2Yb·DME was synthesized by the reaction of YbCl 3 with K(2,4 C 7H 11 )(2,4 dimethylpentadienyl potassium), and the single crystal X ray diffraction showed that the complex exists in a cis staggered conformation. The crystal of the compound belongs to the monoclinic space group P2 1/n with a =0.875 2 (1) nm, b =1.490 6(1) nm, c =1.529 3(2) nm, β =97 55(2)° , V =1.977 79(4) nm 3, Z =4, F (000)=735.8 e, μ =49.49 cm -1 , R =0.033 and R w=0.032 . The title complex can be used as a catalyst for the polymerization of methyl methacrylate(MMA).
