Abstract

Abstract 5,6-DiphenyI-2,3-dihydro(asym)triazine-3-thione can be used as a gravimetric reagent for the determination of rhenium (4–50 mg) in the presence of 0.7–1.7 M hydrochloric acid and tin(II) chloride. The composition of the dried complex, which can be weighed directly, is [ReO(C 15H 10N 3S) 2] 2. The method is simple and rhenium can be determined in the presence of a number of foreign ions.
