Strontium nitrides

Magnesium reacts slowly at lower temperatures to give the amide, as do all active metals this reaction is catalyzed by transition metal ions. Aluminum nitride [24304-00-5] AIN, barium nitride [12047-79-9] Ba2N2, calcium nitride [12013-82-0] Ca2N2, strontium nitride [12033-82-8], Sr2N2, and titanium nitride [25583-20-4], TiN, may be formed by heating the corresponding amides. 

Sr3N2 (c). Guntz and Benoit1 measured the heat of solution of strontium nitride in aqueous HC1. 

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.

Most of the anionic 16-valence-electron species that are isoelectronic to CO2 and CS2 were synthesized by high-temperature solid-state reactions in ampules made of the refractory metal niobium or tantalum. For example, the compounds Sr3(BN2)2 and K3(BP2) were prepared at 1000°C from strontium nitride and graphitic BN, or from...
