Degradation of silicone grease by Grignard reagents: bis(mu-dimethylphenylsilanolato-kappa2O:O)bis[bromido(diethyl ether)magnesium(II)].
The title compound, [Mg2Br2(C8H11OSi)2(C4H10O)2], was obtained by slow dissolution of silicone grease in a diethyl ether solution of phenylmagnesium bromide. The molecules lie about inversion centres and do not display any short intermolecular interactions. There are only a handful of crystal structures of triorganosiloxomagnesium complexes reported previously, and the structure also illustrates the type of species that may be present in solution after accidental contact of Grignard reagents with silicon grease.
