Several of these phosphorus sulfides are produced commercially for industrial applications. P4S3 is one of the key chemical constituents of strike-anywhere matches and has been used industrially for this purpose ever since 1898. P4S10 is the most widely industrially used of the phosphorus sulfides with applications in the preparation of lubricant additives and pesticides and in organic chemistry to convert carbonyl or alcohol groups into their sulfur analogues (see Section 5.4). 

The heavier chalcogen and pnictogen analogues of many of these phosphine sulfides are also known (Table 1). 

Antimony and bismuth sulfides and selenides (Sb2S3, 61283 and Sb2Se3) are also known although these do not exist as discrete molecular compounds, but instead form ribbon-like polymeric structures where each group 15 atom is bound to three group 16 atoms and vice-versa to give an array of interlocking pyramids.
