The structure described by Sr2MgN2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded to five equivalent N(1) atoms to form a mixture of edge and corner-sharing SrN5 square pyramids. Mg(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to five equivalent Sr(1) and one Mg(1) atom to form a mixture of distorted edge and corner-sharing NSr5Mg octahedra. The corner-sharing octahedral tilt angles range from 0-12°. is represented by the CIF file [CIF]
