Abstract

Abstract:(CSMes) 2Sm (THF) 2 reduces AlMe, in toluene to form (C, Me,), Sm [(p-Me) A1Me2 (p-Me) l2Sm (CSMes),(l), which crystallizes from toluene in space group P2,/n with unit cell parameters a= 12.267 (3) A, b= 12.575 (3) A, and c= 17.131 (2) A and z= 2 for Dcalcd= 1.30 g cm-,. Least-squares refinement of the model based on 2163 observed reflections converged to a final RF= 5.7%. Each trivalent bent metallocene (CsMe5) 2Sm unit in 1 is ...
