The material structure described by Sr3N2 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. Sr(1) is bonded to one N(2) and three equivalent N(1) atoms to form a mixture of edge and corner-sharing SrN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to six equivalent Sr(1) atoms to form a mixture of distorted edge and corner-sharing NSr6 octahedra. The corner-sharing octahedral tilt angles range from 52-53°. In the second N site, N(2) is bonded to six equivalent Sr(1) atoms to form a mixture of edge and corner-sharing NSr6 octahedra. The corner-sharing octahedral tilt angles are 53°. is represented by the Crystallographic Information File (CIF) [CIF]
