Structure of Sulphides
Sulphides have a wide range of structures, including molecular and polymeric bridges, and may be found in both nonmetals and metalloids.
Phosphorus has stable molecular chains of sulphides. Variants such as P4S4, P4S3, P4S7, P4S5, and P4S9 are derived from a tetrahedral P4 molecular structure in which the initial P-P bonds are converted into P-S-P bonds. Notably, these phosphorus sulphides have low reactivity except with water, where they produce hydrogen sulphide (H2S) and phosphoric acid (H3PO4), as seen in:
P4S10 + 16 H2O = 10 H2S + 4 H3PO4
Silicon disulfide, a metalloid, has a unique structure with numerous SiS4 polymer chains. Each chain is made up of tetrahedrons, with silicon atoms covalently bonding with sulphur atoms at each edge.
Sulphide
Sulphide is a chemical product generated when sulphur reacts with another element, usually a metal. It is frequently found in minerals such as pyrite (fool’s gold) and galena. Sulphides frequently emit unique odours (such as rotten eggs), and some are hazardous. They have a variety of purposes in industry, including mining for metals such as copper and lead. Sulphides also have a role in natural processes such as volcanic gas production and some biological activities.
