Abstract

(Figure Presented) Shape-shifter: The beryllium allyl complex [Be{1,3-(SiMe3)2C3H3} 2(Et2O)] (see picture) has been synthesized and its X-ray structure determined. Although the allyl ligands are o bonded, the molecule is fluxional in solution, and it engages in a Schlenk equilibrium with BeCl 2. DFT calculations suggest that in the absence of a coordinated base, both σ- and π-bound forms would be potential energy minima.
