The trifluorosilicon(IV) cation [SiF3(Me3tacn)]+, isolated as salts with [SiF5]−, [B{3,5-(CF3)2C6H3}4]− or Cl−, is obtained by reaction of SiF4 with Me3tacn under anhydrous conditions, and compared with the tetrafluoro complexes [SiF4(tmeda)] and [SiF4{κ2-Me2N(CH2)2NMe(CH2)2NMe2(CH2Cl)}][SiF5] obtained with the acyclic di- and tri-amines.
