Abstract
The crystalline magnesium compounds Mg[Si(SiMe3)(3)](2)(thf)(2) (1) and MgB r[Si(SiMe3)(3)](thf)(2) (2) are obtained in high yield from MgBr2 and the L i or K sisyl in appropriate stoichiometry in Et2O or thf; NMR spectra and X -ray crystal data for 1 and 2 confirm their structures; for 1: Mg-Si 2.682( 2) Angstrom, Si-Mg-Si' 131.19(15)degrees.
