摘要：

Magnesium and zinc alkyl complexes supported by the phenyltris(3-t-butylpyrazolyl)borato ligand, [PhTp(But)]MgR (R = Me, Et) and [PhTp(But)]ZnEt, have been synthesized by reaction of [PhTp(But)]T1 with R2M (M = Mg, Zn). Comparison of the structures of [PhTp(But)]MMe with those of [TpB(ut)]MMe indicates that the phenyl substituent on boron has an almost negligible effect on the Mg-C and Zn-C bond lengths.
