2. Phosphorus sesquisulfide is used in making safety matches.
3. In match tips.
General Description
A yellow crystalline solid. Easily ignited by friction. Forms sulfur dioxide and phosphorus pentaoxide during combustion. Reacts with water to form phosphoric acid, a corrosive material. Used to make matches and in the manufacture of other chemicals.
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.
Reactivity Profile
PHOSPHORUS SESQUISULFIDE is a reducing agent.
Health Hazard
Different sources of media describe the Health Hazard of 1314-85-8 differently. You can refer to the following data:
1. Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
2. Phosphorus sesquisulfide exhibited low to moderate acute oral toxicity in animals. An oral dose lethal to rabbits was reported to be 100 mg/kg (NIOSH 1986). Because of its low vapor pressure, any health hazard due to inhalation of this compound in the work place should be very low. There is no report on its acute inhalation toxicity. Its vapors may produce irritation of respiratory passage. Skin contact may cause mild irritation. It produces toxic sulfur dioxide on burning.
Fire Hazard
Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Containers may explode when heated. Runoff may create fire or explosion hazard.
Flammability and Explosibility
Flammable
Safety Profile
Poison by ingestion.
Flammable by spontaneous ignition. When
heated to decomposition it emits very toxic
fumes of POx and SOx. See also SULFIDES
and PHOSPHORUS.
Purification Methods
Extract P4S3with CS2, filter it and evaporate it to dryness. Alternatively place it in H2O, and pass steam through it for an hour. The H2O is then removed, the solid is dried, and recrystallised from CS2 [Rogers & Gross J Am Chem Soc 74 5294 1952].
Waste Disposal
An alkaline solution is treated with laundry bleach, allowed to stand overnight, neutralized, and washed down the drain with plenty of water.
Check Digit Verification of cas no
The CAS Registry Mumber 1314-85-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1314-85:
(6*1)+(5*3)+(4*1)+(3*4)+(2*8)+(1*5)=58
58 % 10 = 8
So 1314-85-8 is a valid CAS Registry Number.

, p. 693 - 697 (1999)
The reaction of P4E3 (E = S, Se) with NbCl5 yields [β-P4S4(NbCl5)2] and [P4Se3(NbCl5)]. [β-P4S4(NbCl5)2] crystallizes in the monoclinic space group P21/n with the lattice parameters a = 6.226(1), b = 12.971(2), c = 26.380(2) A, β = 93.7(1) (Z = 4). In this compound a sulfur atom is introduced into the basal P3-ring and the resulting β-P4S4 is central unit of the complex. [P4Se3(NbCl5)] crystallizes in the same space group type with the lattice parameters a = 11.939(1), b = 18.603(2), c = 12.763(4) A, β= 90.16(2)° (Z = 8). In both compounds the ligands are coordinated to basal phosphorus atoms.
Synthesis of cationic R2P5+ cages and subsequent chalcogenation reactions

Cationic R2P5+ cage compounds (1 +) have been synthesized by the stoichiometric reaction of R 2PCl, GaCl3 and P4. The reaction conditions depend on the substituent R. Alkyl-substituted derivatives (1 a-1 d[GaCl 4]) are best synthesized under solvent-free conditions, whereas aryl-substituted derivatives (1 e-1 h[GaCl4]) are formed in C 6H5F. All compounds have been prepared on a multi-gram scale in good to excellent yields and have been fully characterized with an emphasis on 31P NMR spectroscopy in solution and single-crystal structure determination. Subsequent chalcogenation reactions of cations R 2P5+ (1 a+, 1 e+) and trication Ph6P73+ (33+) with elemental sulfur (α-S8) or grey selenium (Segrey) yielded a series of unique polyphosphorus-chalcogen cations (4 a+, 4 e+, 5 a+, 62+ and 72+ Copyright
