Über ein neues Pernitrid des Strontiums und Calciums und über die Imide der Erdalkalimetalle

Abstract: Neben den einfachen Oxyden und Sulfiden der Alkali-und Erdalkalimetalle sind seit langem auch deren mannigfaltige Peroxyde und Polysulfide bekannt. Es erschien daher reizvoll zu untersuchen, ob nicht der im periodischen System zwischen Sauerstoff und Schwefel stehende Stickstoff uber die normalen, wahrscheinlich salzartigen Nitride der Erdalkalimetalle hinaus auch zur Bildung von stickstoffreicheren ,,Pernitriden" fiihig sei. Wie im folgenden gezeigt wird, ist es in der Tat gelungen, zunachst ein uber 90% rein… Show more

“…Because the amount of europium within the sample is quite low, the endothermic peak of Eu(NH 2 ) 2 dissociation will probably be covered by the strong signals (1 and 2) of Ba(NH 2 ) 2 . Around 440 °C (3), the onset of the decomposition of Sr amide to the respective imide is observed . At higher temperatures around 590 °C (4), the endothermic signal indicates the starting reaction of the imides and formation of the respective nitrides.…”

“…Four different thermal events can be identified as marked in figure . The endothermic peaks between 290 and 310 °C (1 and 2) can be attributed to the degradation of barium amide to barium imide . Because the amount of europium within the sample is quite low, the endothermic peak of Eu(NH 2 ) 2 dissociation will probably be covered by the strong signals (1 and 2) of Ba(NH 2 ) 2 .…”

“…The first report of a nitrogen-rich barium nitride dates from as early as 1892 . In 1934, the nitrides of M 3 N 4 stoichiometry were reportedly obtained for Ba, Sr, and Ca by decomposing the respective amides in a vacuum . In the 1950s, the first high-pressure experiments were attempted, which resulted in the preparation and characterization of BaN 2 .…”
