}} Sulfur tetrachloride is an inorganic compound with chemical formula SCl4. It is an unstable pale yellow solid, decomposing to sulfur dichloride and chlorine at temperatures above 242 K. It is obtained by treating sulfur dichloride with chlorine at 193 K: : Its solid structure is uncertain. It is probably the salt SCl3+Cl−, since related salts are known. ==Characteristics== Sulfur tetrachloride is stable in solid state below −30 °C and decomposes to chlorine and sulfur when temperature rises. In solid state, there is a white, finely powdered substance. It melts with simultaneous decomposition above −20 °C.〔Georg Brauer: ''Handbuch der Präparativen Anorganischen Chemie''. 〕 Sulfur tetrachloride reacts with water, producing hydrogen chloride and sulfur dioxide through the hydrolysis process.〔Holleman-Wiberg, Lehrbuch der Anorganischen Chemie, 101. Auflage, de Gruyter Verlag 1995 ISBN 3-11-012641-9 〕 Gas-phase SCl4 has a seesaw molecular geometry as evidenced from microwave spectroscopy and electron diffraction.〔Goettel, J. T., Kostiuk, N. and Gerken, M. (2013), ''The Solid-State Structure of SF4: The Final Piece of the Puzzle'' . Angew. Chem. Int. Ed., 52: 8037–8040. 〕 The liquid has a fluxional trigonal bipyramidal geometry with rapid exchange of the axial and equatorial fluorine atoms on the NMR timescale at room temperature.〔 For the solid state a structure has been reported consisting of a SCl4 seesaw geometry〔 linked in a three-dimensional network by weak S–F interactions, two per molecule. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sulfur tetrachloride」の詳細全文を読む スポンサード リンク
