摘要：

The alkaline earth metal nitride compounds Ca2N, Sr2N, (Sr0.48Ba0.52)(2)N, Ba2N, Sr2NCl and Sr2NBr have been synthesized and investigated by the means of X-ray diffraction. These compounds all have crystal structures closely related to the anti-alpha-NaFeO2 Structure type. The reaction products obtained from the nominal starting compositions "Ca2NHx" (0 less than or equal to x less than or equal to 1) were also analyzed by X-ray powder diffraction. With x greater than or equal to 0.75, Ca2NH1-delta is the only product observed, but for x < 0.75, Ca2N is found in equilibrium with Ca2NH1-δ. An overview Of M2NX and alkaline earth metal subnitride compounds compares the present results to literature data. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
