The complex of [(t-C4H9C5H4)2Yb(THF)2][BPh4] · THF (1) has been synthesized by one-electron oxidation of (t-C4H9C5H4)2Yb(THF)2 (2) with AgBPh4. 1 crystallized from THF-toluene in space group P2/n (#13) with unit cell constants: a = 12.362(9) A, b= 14.855(5) A, c = 14.093(6) A, β = 109.20(4)°, V= 2444(2) A3 and Z=2 for Dcalc = 1.292 g cm-3. Least squares refinement of the model based on 2257 observed reflections led to final R of 0.046. This complex shows catalytic activity for the polymerization of styrene at high temperature.
