MoS6
MoS6 is a metastable, sulfur-rich transition-metal compound that exhibits semiconducting properties.
About MoS6
MoS6 is a sulfur-rich member of the transition-metal dichalcogenide family, characterized by a higher sulfur-to-molybdenum ratio than typical stable phases. It exhibits a semiconducting electronic profile, making it a subject of interest for researchers exploring non-stoichiometric metal sulfides.
Due to its position above the thermodynamic hull, this compound is considered metastable, reflecting the synthetic challenges in stabilizing such high-sulfur configurations. It remains a notable entry in structural databases, representing the diverse compositional space accessible within molybdenum-sulfur systems.
Key Properties
Cross-validated computational properties for MoS6, aggregated across 2 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the transition-metal dichalcogenides class.
Unlike the highly stable and widely utilized MoS2, which serves as the prototypical semiconductor in this class, MoS6 represents a more exotic and less thermodynamically favored stoichiometry. While siblings like MoSe2 and MoS2 are prized for their robust layered structures, MoS6 occupies a more complex structural landscape, highlighting the distinct stability boundaries that exist when moving away from traditional dichalcogenide ratios.
