Triphosphorus pentanitride is an inorganic compound with the chemical formula P3N5. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. Related compounds are boron nitride and silicon nitride. No applications have been developed for this material, which remains a topic of research. It is a white solid, although samples often appear colored owing to impurities. == Synthesis == Triphosphorus pentanitride can be produced by reactions between various phosphorus(V) and nitrogen compounds (such as ammonia and sodium azide);〔 including a reaction between the elements. :3 PCl5 + 5 NH3 → P3N5 + 15 HCl :3 PCl5 + 15 NaN3 → P3N5 + 15 NaCl + 5 N2 Similar methods are used to prepared boron nitride and silicon nitride; however the products are generally impure and amorphous. Crystalline samples have been produced by the reaction of ammonium chloride and hexachlorocyclotriphosphazene: or phosphorus pentachloride.〔 :(NPCl2)3 + 2 NH4Cl → P3N5 + 8 HCl :3 PCl5 + 5 NH4Cl → P3N5 + 20 HCl P3N5 has also been prepared at room temperature, by a reaction between phosphorus trichloride and sodium amide. :3 PCl3 + 5 NaNH2 → P3N5 + 5 NaCl + 4 HCl + 3 H2 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Triphosphorus pentanitride」の詳細全文を読む スポンサード リンク
