Strontium nitride hydride

Strontium is so active it must be stored under kerosene or mineral oil. In this way, the metal does not come into contact with air. In a finely divided or powdered form, strontium catches fire spontaneously and burns vigorously. Strontium is active enough to combine even with hydrogen and nitrogen when heated. The compounds formed are strontium hydride (SrH2) and strontium nitride (Sr3N2). Strontium also reacts with cold water and with acids to release hydrogen gas ... 

Silvery-white metal face-centered cubic structure rapidly becomes yellow on exposure to air and assumes an oxide film. The finely divided metal ignites spontaneously in air. d 2.6 mp 757 I bp 1366. E (aq) SF+ /Sr -2.89 V. For a description of reactions which are characteristic of at -kaline earth metals see Calcium. Keep under liquid containing no oxygen. The heated metal combines with hydrogen to form strontium hydride and with nitrogen to form strontium nitride. Strontium salts impart brilliant red color to a flame. 

STRONTIUM NITRATE or STRONTIUM(II) NITRATE (10042-76-9) Sr(NOj)2 Noncombustible solid. A powerful oxidizer accelerates the burning of combustible materials. Reacts violently with reducing agents, including hydrides, nitrides, and sulfides, acetic anhydride, tert-butylhydroperoxide, cyanides, halogens hydrazines thiocyanates, sodiiun acetylide stannous chloride. Mixtures of nitrates with alkyl esters may form explosive alkyl...
