The crystal structure described by Sr2SnN2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded to five equivalent N(1) atoms to form a mixture of corner and edge-sharing SrN5 square pyramids. Sn(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to five equivalent Sr(1) and one Sn(1) atom to form a mixture of corner and edge-sharing NSr5Sn octahedra. The corner-sharing octahedral tilt angles range from 0-4°. is represented by the Crystallographic Information File (CIF) [CIF]
