Addition of a thiocyanate salt to a solution containing ferric ions gives a deep red color. The identity of the chromophore remains unknown. [15] The reverse was also used: testing for the presence of thiocyanate by the addition of ferric salts. The 1:1 complex of thiocyanate and iron is deeply red. The effect was first reported in 1826. [16]
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°.
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.
Mercury(II) thiocyanate (Hg(SCN) 2) is an inorganic chemical compound, the coordination complex of Hg 2+ and the thiocyanate anion. It is a white powder. It is a white powder. It will produce a large, winding "snake" when ignited, an effect known as the Pharaoh's serpent .
Nickel(II) thiocyanate is a coordination polymer with formula Ni(SCN) 2. [1] It is a green-brown solid and its crystal structure was determined first in 1982. [1]
Copper(II) thiocyanate (or cupric thiocyanate) is a coordination polymer with formula Cu(SCN) 2. [1] It is a black solid which slowly decomposes in moist air. [ 2 ] It was first reported in 1838 by Karl Ernst Claus and its structure was determined first in 2018.
Cobalt(II) thiocyanate is an inorganic compound with the formula Co(SCN) 2. [1] The anhydrous compound is a coordination polymer with a layered structure. The trihydrate , Co(SCN) 2 (H 2 O) 3 , is a isothiocyanate complex used in the cobalt thiocyanate test (or Scott test ) for detecting cocaine .
