<p>Phosphorus pentasulfide is the <a href="/facts/Inorganic_compound/TfFfzxSz">inorganic compound</a> with the formula P2S5 (<a href="/facts/Empirical_formula/xd0vSIlm">empirical</a>) or <a href="/facts/Phosphorus/27xCeIqs">P</a>4<a href="/facts/Sulfur/IK0amTfM">S</a>10 (<a href="/facts/Molecular_formula/hghUtthl">molecular</a>). This yellow solid is the one of two <a href="/facts/Phosphorus_sulfide/W7bEcQpx">phosphorus sulfides</a> of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in <a href="/facts/Carbon_disulfide/b04Tadmy">carbon disulfide</a> but reacts with many other <a href="/facts/Solvents/LoMPMz8S">solvents</a> such as <a href="/facts/Alcohols/Y0SCTDkh">alcohols</a>, <a href="/facts/DMSO/T4HSYfuC">DMSO</a>, and <a href="/facts/Dimethylformamide/wjI8UfB4">DMF</a>. </p>
