Calcium nitride - Wikipedia
Structure α-Calcium nitride adopts an anti-bixbyite structure, similar to Mn 2 O 3, except that the positions of the ions are reversed: calcium (Ca 2+) take the oxide (O 2−) positions and nitride ions (N 3−) the manganese (Mn 3+).In this structure, Ca 2+ occupies tetrahedral sites, and the nitride centres occupy two different types of octahedral sites.
