WebStahl, 1942). These effects were unpredictable in occurrence, even when blood thiocyanate levels were monitored to control the dose. The mechanism of the antihypertensive effects of thiocyanate is not presently known. Of particular note were the reports of effects of thiocyanate exposure on the thyroid. WebThe thiocyanate group has been studied in detail as a ligand for lanthanide (III) ions in recent years. Recent extensive studies by Japanese workers in particular have shown that the stoichiometry and structure of the anionic complex obtained depends greatly upon factors such as the counter ion used, upon the solvent employed, etc.
Das Thiocyanation (SCN ) kann als Ligand in Komplexen sowohl über das Stickstoff- als auch über das Schwefelatom an das Zentralatom koordinieren. In seinem chemischen Verhalten ähnelt es den Halogenen und wird daher seit 1925 zur Gruppe der Pseudohalogene gezählt.
