Darstellung und Kristallstruktur von Tetramethylammoniumbromid‐Brom‐SO2‐Addukt, [(CH3)4N]+Br‐�Br2�2SO2

Preparation and Crystal Structure of Tetramethylammoniumbromide‐Bromine‐Sulfur Dioxide Adduct, [(CH₃)₄N]⁺Br^‐�Br₂�2SO₂ Tetramethylammoniumtribromide forms with sulfur dioxide a salt which is characterized by vibrational spectroscopy and crystal structure analysis. [(CH₃)₄N]⁺Br^‐�Br₂�2SO₂ crystallizes monoclinic in the space group P2₁/m with a = 657.4(5) pm, b = 2933.0(5) pm, c = 1462.2(5) pm, β = 91.241(5)° and four formula units in the unit cell. The crystal structure possesses bent infinite chains which consist of alternately arranged bromine and bromide ions. The bromide ions are connected to the molecules of bromine and sulfur dioxide by strong interactions forming a three dimensional network.
