It was developed by Henri Sevene and Emile David Cahen in 1898 as part of their invention of friction matches that did not pose the health hazards of white phosphorus. Both PS bond lengths are 212 Å.
The structure is zero-dimensional and consists of four P4S7 clusters.
P4s7. A Berzelius Reagent Phosphorus Decasulfide P4S10 in Organic Syntheses. 1 mole is equal to 1 moles P4S7 or 348350044 grams. The form in which the non-volatile sulphur is present in the hydrolysate is not certain.
Phosphorus sulfide P4S7 Tetraphosphorus heptasulphide. In the first P350 site P350 is bonded in a water-like geometry to two S2- atoms. The P4-S7 molecule contains a total of 13 bond s There are 13 non-H bond s 1 multiple bond s 1 double bond s 4 six-membered ring s 3 eight-membered ring s 3 phosphite sthiophosphite s and 1 phosphate sthiophosphate s.
Amorphous P4S7 was obtained by quenching melted P4S7 in liquid nitro- gen. We assume you are converting between moles P4S7 and gram. Tetraphosphorus Heptasulfide P4S7 Molar Mass Molecular Weight.
Images of the chemical structure of P4-S7 are given below. A compound is a substance made up of a definite proportion of two or more elements. This article is cited by 4 publications.
Grams P4S7 to molecule Details on molecular weight calculations In chemistry the formula weight is a quantity computed by multiplying the atomic weight in atomic mass units of each element in a chemical formula by the number of atoms of that element present in the formula then adding all of these products together. Easily ignited by friction. Tetraphosphorus Heptasulphide or Phosphorus Tetritaheptasulphide P 4 S 7 was first obtained during the distillation of P 4 S 6 in a vacuum and was separated by heating under pressure with carbon disulphide in which as distinguished from P 4 S 3 it was only sparingly solubleIn the methods of preparation which have been described the phosphorus should.

The P4-S7 molecule contains a total of 13 bond s There are 13 non-H bond s 1 multiple bond s 1 double bond s 4 six-membered ring s 3 eight-membered ring s 3 phosphite sthiophosphite s and 1 phosphate sthiophosphate s. Turan Ozturk Erdal Ertas and Olcay Mert.
A chemical formula tells us the number of atoms of each element in a compound. There is fair agreement between these results and those of earlier work. There are four inequivalent P350 sites.
Reacts with water to form phosphoric acid a corrosive materialUsed to make matches and in the manufacture of other chemicals. You can view more details on each measurement unit.

The following phosphorus sulfides are known. P4S3 P4S7 and P4S10. The SI base unit for amount of substance is the mole.
From Wikipedia the free encyclopedia Phosphorus sesquisulfide is the inorganic compound with the formula P 4 S 3. P4s7 35 points 36 points 37 points 2 months ago The saddest moment for a support is stacking jungle camps and watch your enemy come and farm it all cuz your cores never farmed it all game. Phosphorus sulfide P4S7 What information about the compound is not part of a chemical formula.
P4S7 is High Pressure 4-7GPa Tellurium structured and crystallizes in the monoclinic P2_1c space group. Reacts with liquid water or atmospheric moisture to form toxic hydrogen sulfide gas and corrosive phosphoric acid. Phosphorus sesquisulfide free from yellow and white phosphorus appears as a yellow crystalline solid.
Molecular weight of P4S7 or grams This compound is also known as Phosphorus Heptasulfide. All spectra were recorded on a Bruker AC 250 spectrometer operating at 1013 MHz for 31P and the chemical shifts were referenced to 85 D3P04 used as an external standard. Phosphorus heptasulfide free from yellow or white phosphorus.
