The compound described by Sr2NI is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent I(1) atoms. N(1) is bonded to six equivalent Sr(1) atoms to form edge-sharing NSr6 octahedra. I(1) is bonded in a 6-coordinate geometry to six equivalent Sr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
