Thionyl fluoride is a chemical compound from the group of thionyl halides .

Extraction and presentation

Thionyl fluoride can be obtained by reacting thionyl chloride with hydrogen fluoride or sodium fluoride .

{\ displaystyle \ mathrm {SOCl_ {2} +2 \ HF \ longrightarrow SOF_ {2} +2 \ HCl}}

{\ displaystyle \ mathrm {SOCl_ {2} +2 \ NaF \ longrightarrow SOF_ {2} +2 \ NaCl}}

The simplest representation in the laboratory is the reaction of thionyl chloride with antimony (III) fluoride in the presence of antimony (V) chloride as a catalyst :

{\ displaystyle {\ ce {3 SOCl2 + 2 SbF3 -> [SbCl_5] [] 3 SOF2 + 2 SbCl3}}}

properties

Bond lengths and angles of thionyl fluoride

Thionyl fluoride is a colorless gas that is thermally resistant to red heat. Base metals such as magnesium , nickel , mercury and aluminum are not attacked in a dry atmosphere of up to 125 ° C. While glass is attacked from 400 ° C, no reaction occurs with iron at this temperature. It is only slowly hydrolyzed by ice-cold water and smokes lightly on contact with moist air. In the solid state it has a monoclinic crystal structure with the space group P 2 ₁ / c (space group no. 14) . It reacts with fluorine to form thionyl tetrafluoride F ₄ SO. It is readily soluble in diethyl ether and benzene . Template: room group / 14
