Compounds of rhenium and sulfur include rhenium sulfides in the oxidation states II, IV, and VII. [Rhenium(II) sulfide] Chemical formula: ReS. It is obtained by reacting a mixture of hydrogen sulfide and hydrogen gas with rhenium(VI) oxide (ReO 3) at 90 °C. Specific gravity: 7.42. It is stable in argon up to about 1000 °C. When it reacts with hydrogen, it becomes rhenium and hydrogen sulfide at 280 °C. [Rhenium(IV) sulfide] Chemical formula: ReS 2. It can be obtained by mixing ReO 3 and sulfur and heating it in a vacuum at 400°C for 24 hours. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
