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°.
[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. [11] [12] Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter. [13] Iodine is an essential component of thyroxine. Since thiocyanates will ...
Thiocyanic acid has been observed spectroscopically. [12] The salts and esters of thiocyanic acid are known as thiocyanates. The salts are composed of the thiocyanate ion ([SCN] −) and a suitable cation (e.g., potassium thiocyanate, KSCN). The esters of thiocyanic acid have the general structure R−S−C≡N, where R stands for an organyl group.
By contrast, in methyl thiocyanate, N≡C and C−S distances are 116 and 176 pm. Typical bond angles for C−N=C in aryl isothiocyanates are near 165°. Again, the thiocyanate isomers are quite different with C−S−C angle near 100°. [3] In both isomers the SCN angle approaches 180°.
Thiocyanate complexes are not widely used commercially. Possibly the oldest application of thiocyanate complexes was the use of thiocyanate as a test for ferric ions in aqueous solution. [14] 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.
Examples of linkage isomers are violet-colored [(NH 3) 5 Co-SCN] 2+ and orange-colored [(NH 3) 5 Co-NCS] 2+. The isomerization of the S-bonded isomer to the N-bonded isomer occurs intramolecularly. The isomerization of the S-bonded isomer to the N-bonded isomer occurs intramolecularly.
New Jersey gambling regulators have handed out $40,000 in fines to two sportsbooks and a tech company for violations that included taking bets on unauthorized events, and on games that had already ...
