Structure of Pd(Me 2 N(CH 2) 3 PPh 2)(SCN)(NCS) illustrating linkage isomerism of the SCN ...
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.
Thiocyanogen, (SCN) 2, is a pseudohalogen derived from the pseudohalide thiocyanate, [SCN] −, with behavior intermediate between dibromine and diiodine. [2] This hexatomic compound exhibits C 2 point group symmetry and has the connectivity NCS-SCN. [3] In the lungs, lactoperoxidase may oxidize thiocyanate to thiocyanogen [4] or ...
Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
HSAB is an acronym for "hard and soft (Lewis) acids and bases".HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species.
Ammonium thiocyanate is used in the manufacture of herbicides, thiourea, and transparent artificial resins; in matches; as a stabilizing agent in photography; in various rustproofing compositions; as an adjuvant in textile dyeing and printing; as a tracer in oil fields; in the separation of hafnium from zirconium (important for the production of hafnium-free zircalloy for use in nuclear fuel ...
The esters of thiocyanic acid have the general structure R−S−C≡N, where R stands for an organyl group. Isothiocyanic acid, HNCS, is a Lewis acid whose free energy, enthalpy and entropy changes for its 1:1 association with a variety of Lewis bases in carbon tetrachloride solution at 25 °C have been reported.
The cyanate ion is an isomer of the much-less-stable fulminate anion, CNO − or [C − ≡N + −O −]. [ 1 ] The cyanate ion is an ambidentate ligand , forming complexes with a metal ion in which either the nitrogen or oxygen atom may be the electron-pair donor .
