  Elementorganisch substituierte Ammonium-Salze. Die Kristallstrukturen von [HN(SnMe3)3]I, [H2N(SnMe3)2][SnMe3Cl2] und [N(AsMe3)2]Br

  摘要：

  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 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 P2(1)3, Z = 8; lattice dimensions at -50 degrees 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, Pca2(1), Z = 4; lattice dimensions at -60 degrees C a = 1373.2, b = 762.2, c = 1951.5 pm. The structure consists of [H2N(SnMe3)(2)](+) and [SnMe3Cl2](-) ions, which are associated to chains via interionic Sn ... Cl contacts.3: Space group I4(1)/a, Z = 8; lattice dimensions at -50 degrees 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 degrees.
