Weakly coordinating anions and nonpolar solvents facilitate the isolation of the first NH 4 + and PH 4 + derivatives completely substituted with main group organometallic units. The triflate and BPh 4 salts of the [E(SnMe 3 ) 4 ] + ions (E=N, P) undergo a rapid Me 3 Sn + ion exchange in THF and thus represent base‐stabilized stannylium ions. The structure of the cation in [N(SnMe 3 ) 4 ] + [OSO 2 CF 3 ] − is depicted.
