Thiocyanatoiron (systematically named thiocyanatoiron(2+)) is a inorganic cation with the chemical formula [Fe(SCN)]2+. It is known to produce a blood red color in solution. This is used as a test for Fe3+ in the laboratory. Fe3+ reacts with thiocyanate to give a series of intensely red colored compounds which remain in the solution and does not undergo any reaction after the formation of the stable octahedral structure.
