Amidomagnesium cations
We report the synthesis, structure and reactivity of molecular amidomagnesium cations bearing tris{2-(dimethylamino)-ethyl}amine (Me 6 TREN). Me 6 TREN binds to the cationic magnesium centre exhibiting κ 4 and κ 3 coordination modes in [Me 6 TREN-Mg-N(SiHMe 2 ) 2 ] + and [Me 6 TREN-Mg-N(SiMe 3 ) 2 ]...
