Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.
In methyl thiocyanate, N≡C and C−S distances are 116 and 176 pm. By contrast, N=C and C=S distances are 117 and 158 pm in isothiocyanates. [7] Typical bond angles for C−S−C are 100°. [3] By contrast C−N=C in aryl isothiocyanates is 165°. Again, the thiocyanate isomers are quite different with C−S−C angle near 100°.
Sodium thiocyanate (sometimes called sodium sulphocyanide) is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion . As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals . [ 2 ]
Strontium thiocyanate refers to the salt Sr(SCN) 2.It is a colorless solid. According to X-ray crystallography, it is a coordination polymer.The Sr 2+ ions are each coordinated to eight thiocyanate anions in a distorted square antiprismatic molecular geometry where each square face contains two adjacent S atoms and two adjacent N atoms.
Calcium thiocyanate refers to the salt Cs(SCN) 2. It is a colorless solid. According to X-ray crystallography, it is a coordination polymer. The Ca 2+ ions are each bonded to eight thiocyanate anions, with four Ca-S and four Ca-N bonds. The motif is reminiscent of the fluorite structure. [1]
Potassium thiocyanate is the chemical compound with the molecular formula KSCN. It is an important salt of the thiocyanate anion , one of the pseudohalides . The compound has a low melting point relative to most other inorganic salts.
Ammonium thiocyanate is an inorganic compound with the formula [NH 4] + [SCN] −. It is an ammonium salt of thiocyanic acid . It consists of ammonium cations [NH 4 ] + and thiocyanate anions [SCN] − .
Thiocyanic acid is a chemical compound with the formula H S C N and structure H−S−C≡N, which exists as a tautomer with isothiocyanic acid (H−N=C=S). [8] The isothiocyanic acid tautomer tends to dominate with the compound being about 95% isothiocyanic acid in the vapor phase. [9] Tautomerism between thiocyanic acid (left) and ...
