TETRATHIOMOLYBDATE

There is only one report of acute poisoning resulting from intake of a dietary molybdenum supplement. The person consumed a total dose of 13.5 mg of molybdenum over a period of 18 days, at an intake rate of 300-800 μg daily, resulting in visual and auditory hallucinations, several petit mal seizures and one grand mal seizure. The subject was treated with chela-tion therapy to remove the molybdenum from his body and his symptoms disappeared after several hours... Ammonium tetrathiomolybdate is the chemical compound with the formula [NH 4] 2 MoS 4. This bright red ammonium salt is an important reagent in the chemistry of molybdenum and has been used as a building block in bioinorganic chemistry. The thiometallate anion has the distinctive property of undergoing oxidation at the sulfur centers concomitant with reduction of the metal from Mo(VI) to Mo(IV). The salt contains the tetrahedral [MoS 4] 2− anion. The compound is prepared by treating solutions of molybdate, [MoO 4] 2− with..
