Rhenium Wikipedia

Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table.With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust.Rhenium has the third-highest melting point and second-highest boiling point of any stable element at 5903 K

Rhenium chemical element Britannica

Rhenium does not occur free in nature or as a compound in any distinct mineral; instead it is widely distributed in small amounts in other minerals, usually in concentrations averaging about 0.001 parts per million. Chile is the world leader in rhenium recovery, followed by the United States, Poland, Uzbekistan, and Kazakhstan.. Rhenium occurs up to about 20 parts per million in molybdenite

In Chemistry of the Elements (Second Edition), 1997. Oxidation state VI (d 1). Again, fluoro and oxo complexes of rhenium predominate. The reaction of KF and ReF 6 in an inert PTFE vessel yields pink K 2 [ReF 8], the anion of which has a square-prismatic structure; hydrolysis converts it to K[ReOF 5].. An interesting compound which is usually included in discussions of Re VI chemistry is the
