摘要：

The synthesis and structure characterization of (Bu2Mg)-Bu-t is reported. The X-ray structure and variable-temperature H-1 and C-13 NMR spectra and the molecular weight measurements show that the title compound occurs as a dimer with a folded CMg(mu-C)(2)MgC skeleton in the solid state and solution. A detailed inspection of the crystal structures of [(Bu2Mg)-Bu-t](2) reveals that intra- and intermolecular CH3...Mg agostic interactions play a substantial role in the molecular assembly.
