Sulfur dicyanide is an
inorganic compound
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...
with the formula S(CN)
2. A white solid, the compound is mainly of theoretical and fundamental interest given its simplicity. It is the first member of the dicyanosulfanes S
x(CN)
2, which includes
thiocyanogen
Thiocyanogen, (SCN)2, is a pseudohalogen derived from the pseudohalide thiocyanate, CNsup>−. This hexatomic compound exhibits C2 point group symmetry and has the connectivity NCS-SCN. The oxidation ability is greater than bromine. It reacts w ...
((SCN)
2) and higher polysulfanes up to S
4(CN)
2. According to
X-ray crystallography, the molecule is planar, the SCN units are linear, with an S-C-S angle of 95.6°. The synthesis of S(CN)
2 is attributed to Söderbäck through his investigation of the reactions of metal cyanides and sulfur halides.
