The stannylated ammonium salt [HN(SnMe3)3]I (1) originates from N(SnMe3)3 and ISnMe3 in n-hexane, while [H2N(SnMe3)2][SnMe3Cl2] (2) is formed as a by-product by the conversion of N(SnMe3)3 with Gallium(III)chloride in CCl4. The complex [N(AsMe3)2]Br (3) with pentavalent arsenic is synthesized by reaction of AsMe3Br2 with N(SnMe3)3 in diethyl ether. 1-3 were characterized by IR spectroscopy and by crystal structure analyses. 1: Space group P213, Z = 8; lattice dimensions at -50°C: a = b = c = 1558.7 pm. The structure consists of two symmetry independent ion pairs with N-H ? I hydrogen bridge contacts. 2: Space group Pca21, Z = 4; lattice dimensions at -60°C: a = 1373.2, b = 762.2, c = 1951.5 pm. The structure consists of [H2N(SnMe3)2]+7 and [SnMe3Cl2]- ions, which are associated to chains via interionic Sn ? Cl contacts. 3: Space group I41/a, Z = 8; lattice dimensions at -50°C: a = b = 826.3, c = 3490.9 pm. 3 consists of bromide ions and cations [N(AsMe3)2]+ with short AsN distances of 175.1 pm along with an AsNAs bond angle of 122.1°.
