Following is the molecular structure of Phosphorus esquisulfide (1314-85-8):

PHOSPHORUS SESQUISULFIDE Uses

Phosphorus esquisulfide (1314-85-8)is used to make matches and in the manufacture of other chemicals.
A 1:2 mixture of Phosphorus esquisulfide (1314-85-8) and potassium chlorate, together with other materials, comprises the heads of "strike-anywhere matches".

PHOSPHORUS SESQUISULFIDE Production

Air & Water Reactions: Highly flammable.Slowly decomposed by water to form phosphoric acid and toxic hydrogen sulfide gas (H₂S). May ignite on contact with water or moist air.

PHOSPHORUS SESQUISULFIDE Standards and Recommendations

DOT Classification: 4.1; Label: Flammable Solid

PHOSPHORUS SESQUISULFIDE Specification

Depending on purity, samples can appear yellow-green to grey. Phosphorus esquisulfide (1314-85-8) was discovered by G. Lemoine and first produced safely in commercial quantities in 1898 by Albright and Wilson. It dissolves in an equal weight of carbon disulfide (CS₂). Unlike some other phosphorus sulfides, P₄S₃ is slow to hydrolyze and has a well-defined melting point.
