It exists in various forms (isomorphs), α-calcium nitride being more commonly encountered. ==Structure== α-Calcium nitride adopts an anti-bixbyite structure, similar to Mn2O3, except that the positions of the ions are reversed: calcium (Ca2+) take the oxide (O2−) positions and nitride ions (N3−) the manganese (Mn3+). In this structure, Ca2+ occupies tetrahedral sites, and the nitride centres occupy two different types of octahedral sites.〔Wells, A.F. (1984) Structural Inorganic Chemistry, Oxford: Clarendon Press.
