Molybdenum sulfides
Molybdenum sulfides are the compounds of the elements sulfur and molybdenum .
By far the most important molybdenum sulfide is molybdenum (IV) sulfide (molybdenum disulfide, molybdenite ) MoS 2 , which is similar to graphite and, like graphite , has a layer structure and is used as a lubricant .
Further known molybdenum sulfides are the trigonal Mo 6 S 8 , which contains a Mo 6 core, and the monoclinic dimolybdenum trisulfide Mo 2 S 3 . In Mo 2 S 3 , the molybdenum atoms are octahedral surrounded by six sulfur atoms and form Mo – Mo zigzag chains. There are also sulphurous molybdenum sulphides which contain SS bridges or anions such as S 2 2− or S 4 2− ; the oxidation state of molybdenum is also in MoS 4 , MoS 5 and MoS 6 with an oxidation number close to 5.
