Molybdenum Disulfide, MoS2: Theory, Structure ...

Molybdenum disulfide belongs to a class of materials called 'transition metal dichalcogenides' (TMDCs). Materials in this class have the chemical formula MX 2, where M is a transition metal atom (groups 4-12 in the periodic table) and X is a chalcogen (group 16). The chemical formula of molybdenum disulfide is MoS 2. The crystal structure of molybdenum disulfide (MoS 2) takes the form of a ...

Molybdenum disulfide - Hyperleap

Molybdenite is a mineral of molybdenum disulfide, MoS 2. The highest oxidation state is seen in molybdenum(VI) oxide (MoO 3 ), whereas the normal sulfur compound is molybdenum disulfide MoS 2. Scheele's analysis showed that the chemical compounds molybdenum sulfide (molybdenite), lead(II) sulfide (galena) and graphite were three different soft black minerals.
