In the crystal structure, each CdIIcation is in a distorted octahedral coordination environment, coordinated by the N and S atoms of nicotinic acid and thiocyanate ligands. Neighbouring CdIIcations are linked together by thiocyanate bridges to form a two-dimensional network. Hydrogen-bond interactions between the uncoordinated

Abstract:
By IR spectrometry thiocyanates aqueous solutions of divalent cations of cadmium, mercury, nickel, manganese, iron, zinc and cobalt were studied. It was found that cadmium (II), mercury (II), nickel (II), iron (II) thiocyanate ions coordinated by type thiocyanate, zinc (II) − according to the type isothiocyanate; cobalt (II) and manganese (II) coordination mode change depending on the concentration of potassium thiocyanate in a solution. These results are consistent with the theory of hard and soft acids and bases. Co2+ ions are intermediate acids, so they can coordinate with SCN− into two typ

Thiocyanates form an important class of organic compounds commonly found in natural products that exhibit excellent antimicrobial activity. The electrophilic thiocyanation is one of the most effective methods of introducing a -SCN functional group to the parent organic molecule. In this work, we explored an eco-friendly and highly efficient method for thiocyanation of anilines and 1-(substituted benzylidene)-2-phenylhydrazines using commercially available N-bromoscuccinimide (NBS) and potassium thiocyanate (KSCN).

Potassium thiocyanate acts as an efficient sulfur surrogate in C–S cross-coupling reactions mediated by recyclable copper oxide nanoparticles under ligand free conditions. This protocol avoids foul smelling thiols, for the synthesis of a variety of symmetrical diaryl sulfides, via the cross-coupling of different aryl halides with potassium thiocyanate, affording corresponding products in moderate to excellent yields.

Abstract:
The alkaloid berberine is useful as a mobile apoplastic tracer. It is readily precipitated by thiocyanate, forming bright yellow, needle-like, fluorescent crystals. When berberine hemisulphate and potassium thiocyanate are applied sequentially to plant tissue, the crystals form in unmodified walls and in the lumina of dead cells such as tracheary elements. Lignified and suberized walls stain with berberine but do not develop crystals. Regions of the plant that have been penetrated by the chemicals can be located by preparing freehand sections, mounting them in potassium thiocyanate to inhibit

Measured speeds of sound, structural relaxation times, and the viscosities of aqueous, methanolic, and propylene carbonate solutions of potassium thiocyanate are reported as functions of concentration (0.0049 ≤ m/mol kg–1 ≤ 22.924) and temperature (273.15 ≤ T/K ≤ 343.15). The primary solvation number of the SCN– ion has been estimated to be 11.6 in a water medium.

Abstract UNS N06690 is one of the current choices for nuclear power plant steam generator tubing. The alloy intensity to some submodes of stress corrosion cracking is a function of sensitization. Sensitization results from chromium carbide precipitation at grain boundaries when the alloy is exposed to temperatures of 500 to 800 °C, causing local chromium depletion in the adjacent zone. The objective of this work was the optimization of the double loop electrochemical potentiokinetic reactivation (DL-EPR) method for UNS N06690.

The majority of the detectable PAI-1 in the ECM formed complexes with tPA indicating that it was active. The resulting tPA/PAI-1 complexes were released from ECM and recovered in the reaction solution indicating that the PAI-1 in such complexes had lost its ECM binding site.
